Hello all!
We started this thread in other forums as a source for members to reference in their tonneau cover buying journey. I wanted to share it here as well since it's been such a helpful tool.
So much has changed in this industry, and several new products have been added that deserve a breakdown. Yet the question remains the same…. “Which cover should I buy?”
While it's impossible to compile every cover and comparison into a single post, I wanted to put together a general guide to assist in planning. I'm going to try to lay this out by style of cover, versus individual cover comparisons as much as possible, without endorsing a specific brand or style. Additionally, there are new covers added every year, and brands/styles that we don't sell, I can't speak to. Please feel free to comment below if you're looking for more in-depth comparisons, specific cover models, suggestions, etc. I'll try and update this post as new covers and styles release in the future to ensure it remains relevant.
A tonneau cover, or truck bed cover as they’re sometimes called, attaches to your truck bed and keeps your gear out of direct rain and snow. Depending on the design, they can also provide outstanding security and even options for additional accessories. This buying guide should help you learn the differences between all the various tonneau cover designs, so you choose the best truck bed cover for your Ram.
The first question I’d ask is, “How do you use your truck?” That helps narrow down which cover materials and designs make the most sense for your daily routine, what you haul, and how you need to access the bed.
Soft Tonneau Covers
The most obvious benefit of choosing a soft truck bed cover is affordability. Soft covers give your cargo ample protection from rain, snow, and other elements at an affordable price. However, not all soft covers are created equally as there are a few different designs to be aware of.
Soft Roll-up
The most widely sold tonneau cover available today, soft rolling covers offer an affordable cover that keeps your gear out of the elements and out of sight. Most designs use heavy-duty hook-and-loop (AKA Velcro) fasteners to secure the tonneau cover once closed and tension from the header bar keeps the cover taut. Once opened, the cover provides full access to the bed, and a fastening system will allow you to keep the cover open when driving. Installation involves clamping a pair of rails to your truck bed and attaching the cover to the rails, a simple process that can usually be done in less than an hour with basic hand tools.
Within the soft rolling category, you have two primary designs. Top mounts and inside mounts. Top mounts have a reputation for being a little more water-resistant due to the design but have a taller profile at about 1.5" above the bed rails. Inside mount covers are going to provide a more aesthetically pleasing look and have a profile on average of .5" above the bed rails.
Additionally, there are several styles of tension controls. The TruXedo Lo Pro, TruXedo Pro X15, and TruXedo TruXport Gen 2 utilize a spring-loaded tension mechanism. This design allows the user to close the cover and not have to worry about adjusting the tension. Most other soft roll-up covers will use a dial or block tension mechanism, i.e. Gator SRX, etc... This style will manually be adjusted, typically at the header bar (front), using a dial. While this design does require manual adjustments periodically, it does allow you to "dial-in" the tautness of the cover to your preference.
Within the soft rolling category, you primarily have two fabric options. Marine-grade vinyl is the most common, used by a variety of brands. This material holds up well to the elements, but if you live in an area with heavy sun, I do recommend occasional treatments with a water-based UV protectant (RealTruck Tire & Vinyl Shine) to help protect the vinyl. The second option would be a fabric, like the TruXedo Pro X15. The benefit of fabric is, it's a matte black finish and can be more heavy-duty. Both options will provide similar water resistance.
Choose a soft rolling tonneau cover if: you want an affordable cover that keeps your gear out of sight and out of the rain while providing full bed access when necessary.
Soft Folding
This truck bed cover is made of vinyl or canvas material stretched over an aluminum frame in a one-piece design. The clamps that attach the cover to your truck bed are part of the cover as well, and they can usually be installed with no tools required. The ease of installation is usually the winning feature: simply line it up on your bed, attach the hand-tightened clamps, and you’re done. To open the cover, simply detach the rear clamps and fold the panel toward your bed for 2/3 bed access. If you need full bed access, the cover can be quickly removed and reinstalled.
Primary differences within the soft folding category will be the style of clamps and top material. The Gator SFX, Extang Trifecta 2.0, and Extang ALX use spring-loaded rear clamps, which allow constant tension to put against the bed rails. Most other soft tri-folds use tension clamps, which will hold the cover against the bed rails. Typically, the more expensive soft folding covers will have wider frames and beefier hinges, designed for increased use and durability compared to the entry-level covers.
Just as with soft roll-up covers, most use marine-grade vinyl, however, one like the Extang Trifecta Signature 2.0 will use a canvas fabric.
Choose a soft-folding tonneau cover if: you want to spend minimal time on installation and protect your cargo from the elements.
Hard Tonneau Covers
While soft covers do a great job of keeping the bed dry with gear out of sight, they do lack the security hard tonneau covers provide. Hardcovers are more water-resistant, made of materials such as aluminum and thermoplastics. Like soft covers, depending on how intend to use your bed will determine which style of hardcover to choose- folding or roll-up.
Hard Folding
Hard folding covers are versatile, relatively easy to install, and easy to operate.
There are two common designs- top mounts and inside mounts. Just like with soft rolling covers, top mounts are going to traditionally be more water-resistant due to their design. Top mount hard folding covers install similarly to a soft folding cover. The cover sits on top of the bed rails and mounts to the lip of the bed, installing in only a few minutes. These covers will fold on top of themselves to provide 2/3 bed access but do require removal to gain full bed access, like with the Extang Solid Fold ALX.
Inside mounts are typically flush with the truck bed rails. Inside mount covers provide a sleek appearance, sitting flush with the bed rails. Common models such as the Undercover Flex line and BakFlip covers will fold up to the cab to give full bed access, without removing. These covers require rails to be installed on each side of the bed, using clamps, and the cover will sit and fold between the rails.
Within the hard folding cover line, you also have a variety of materials to choose from:
Aluminum - Recommended for high UV locations, as aluminum is a more fade-resistant material. Available in satin or matte black finishes in top-mount or inside mount covers. Found on the BAKFlip MX4 Gen 3, BAKFlip MX4 EZ-Lift, BAKFlip MX4 TS, UnderCover Flex, and UnderCover ArmorFlex.
A note on Multi-Shield™: Some hard folding cover also feature Multi-Shield™, a protective finish designed to resist scratches, scuffs, dents, and UV exposure. Found models such as the BAKFlip MX4 TS and UnderCover ArmorFlex.
TPO - EnduraSheild polymer, which is a thermoplastic material that does well-resisting fading and impact. Found on the Extang Solid Fold ALX.
Choose a hard-folding tonneau cover if: you need security, water resistance, and the ability to haul large items when necessary.
Hard Roll-up
While not as well-represented as some other categories, hard roll-up tonneau covers have become a popular alternative to hard folding. The tonneau itself is made of interlocking aluminum slats, which are covered by a heavy-duty vinyl or canvas material. This results in a truck bed cover with no visible hinges that provide ample shielding for items in the bed. Like a soft rolling tonneau cover, opening one of these is as easy as pulling a latch and rolling it toward the bulkhead.
Primary comparisons within this category are between the rail designs and the vinyl type. BAK Revolver series rotational locking rails, in which the cover slats recess into the rail, and a metal latch rotates to cover the slats when locked. This prevents you from being able to lift the cover along the rails at any point. The TruXedo Sentry and TruXedo Sentry CT use heavy-duty hook-and-loop fasteners along the rails to keep the cover secure, with a latch located in the middle of the rail to prevent unwanted access.
Vinyl options include a traditional satin marine-grade vinyl, found on the BAK Revolver X4s, BAK Revolver X2 and TruXedo Sentry.
You’ll find a matte black, premium canvas fabric on the TruXedo Sentry CT.
Choose a hard roll-up tonneau cover if: you like soft cover looks but need hard cover security.
Retractable Tonneau Cover
Not to be confused with roll-up tonneau covers, a retractable tonneau consists of a hard cover made of aluminum or composite material, which retracts into a canister mounted at the bulkhead of the truck bed. Depending on which retractable truck bed cover you choose, you may be able to lock it in position anywhere between open and closed. Typically, designs feature set, intermittent locking points. You can even get an electric retractable tonneau cover that opens via a key fob. Just keep in mind that you’ll lose approximately 10 to 12 inches of overall bed length due to the canister. As mentioned, there are a few differences between models, including locking positions, rails, blanket material, and locking mechanism.
Retrax and GatorTrax covers utilize sealed ball bearings and a springless canister with the intention of being maintenance-free. You don't need to wax the rails, ever replace springs, etc. You’ll "walk the cover back" to the canister, and you can conveniently lock the cover in place anywhere along the truck bed.
Another key difference will be the blanket material, the actual cover itself. Retrax offers both a lighter-duty polycarbonate blanket and a heavy-duty double walled aluminum. For instance, the RetraxONE is made of polycarbonate with aluminum cross beams. The RetraxPRO is made of double-walled aluminum slats.
Similarly, the GatorTrax is constructed of polycarbonate with aluminum cross beams, while the Gator Recoil is an all-aluminum construction.
The final, most notable difference is how they lock. While all retractable covers for modern trucks rely on a closed and locked tailgate, some models include an exterior lock. RetraxPRO, RetraxONE, and GatorTrax have an exterior lock, allowing you to operate the tailgate and cover independently from each other.
The Gator Recoil does not have an exterior lock to open the cover, you’ll have to open the tailgate first. As long as your tailgate is closed and locked, there’s no direct access to the cover.
All that said, there is one retractable tonneau cover on the market that is key lockable, includes recessed T-slot tonneau rails (which I’ll dive into later,) and doesn’t require you to sacrifice any bed space- the RetraxPRO EZ-OFF FRC-4000. Unlike its predecessors, this model allows you to easily remove the canister from the bulkhead of the bed so that you have full bed access when you need it. Simply attach the EZ-OFF™ handles to the canister, detach the upper drain tube from the stationary drain port, remove the pin from the latch on the canister, unlatch the canister and lift it out. Store it out the way and snap it back into place when you need it.
Choose a retractable tonneau cover for convenient operation, adjustable bed access, and if you need something that slides out the way without rolling or folding above the bed.
One-Piece Tonneau Cover
Rather than folding or roll-up to access the truck bed, this design lifts open, often with the assistance of lift supports or scissor hinges. Available in an ABS plastic or ABS composite construction, the one-piece tonneau cover is prized for its unparalleled security and weather resistance, a direct result of its overlapping design. Of course, having the cover painted to match your truck’s OEM paint code also results in an unbeatable look. The one drawback to this design is bed access. To haul large items, you’ll probably have to remove the tonneau cover first. This often requires two people due to the weight and size of the cover.
Choose a one-piece tonneau cover if: you need maximum rain and theft resistance, a color-matching finish, and you don’t plan on hauling large items often.
Tool Box Cover
Right out the gate- let’s clear up some potential confusion. Toolbox tonneau covers do not come with a toolbox. Rather, the cover itself is shorter to accommodate a truck bed equipped with a standard profile, 20-inch toolbox. Do keep in mind, these will not fit low profile toolboxes, as the cover bulkhead rail interferes with the toolbox latches.
There’s the stylish, soft folding Trifecta Toolbox 2.0 or secure hard folding Extang Solid Fold Toolbox 2.0.
Choose a toolbox tonneau cover if: your truck is equipped with a standard 20-inch crossover toolbox.
T-Slot Tonneau Covers
This is a growing category, ranging from soft roll-up to hard roll-up, hard folding and retractable tonneau cover styles. T-slot tonneau covers feature mounting channels along the tonneau rails themselves for compatible racks, crossbars, and cargo accessories. They let you add storage above the bed while keeping cargo covered below. When comparing options, pay attention to the rail design- recessed or raised- as this detail alone can make or break your truck bed build.
Recessed T-Slot Rails
The mounting channel sits within a wider rail profile, with surrounding surfaces that can accommodate compatible rack mounting bases.
This includes most retractable tonneau covers like the RetraPRO XR, RetraxONE XR, EZ-OFF FRC-4000, FlushFit MRC-3000, and FlushFit ERC-4000. Best for low-profile racks.
Raised T-Slot Rails
The mounting channel sits in a raised track above the surrounding rail surface. This design is found on select folding and roll-up covers, as well as add-on T-slot rail systems. Rack mounting bases must accommodate the raised track.
T-slot tonneau covers like the BAKFlip MX4 TS, Revolver X4 TS, and TruXedo ProX15 TS feature this style of rail. Best for height adjustable racks.
Check the Complete Setup
Rack compatibility depends on the specific cover, rail profile, and mounting hardware. Some combinations require an adapter kit, and others allow the rack to mount but prevent the cover from opening- the uprights of the rack can get in the way of the cover panels. Confirm both fitment and cover operation before choosing your setup.
Choose a T-slot tonneau cover if: you want to add a compatible bed rack or other rail-mounted accessories while keeping your truck bed covered.
There’s a lot to sort through, and you’re welcome to ask questions here or DM me to talk through your setup. That’s where my white glove service comes in- taking the time to check the fitment details, explain the tradeoffs, and help you find what works best for the way you use your truck. I’m here to see you through, every step of the way!
Share your own experiences, too. Those are just as helpful to the next member reading. We love to hear how you make the most out of the bed space you have, and how it serves its purpose. Show us what you got!
