Absolutely awesome!
The only drawback with the TRX (i'm sure you're already aware) is the payload is pretty low for a half-ton truck. Your future/second option below mitigates that concern as you can load your gear (food, water, clothes, etc.) in the trailer that you're pulling and just have your family and trailer tongue wait contributing to the payload on the TRX. You get better camping setup and allows you to carry more gear during your outdoor adventure.
When you go with your fist option you're going to max out your payload REALLY fast with tents, gear, food/water, etc. so just be cognizant and stay safe.
On the upkeep of the TRX beauty... many folks are talking about PPF (paint protection films) and ceramic coating, but what I have been relying on is seeing the state's best auto detailer and PDR (painless dent repair) team once per year, and that's been consecutively Man Cave. The only place I will let touch my truck for detailing. These specialize in exotic cars (Mclaren, Lambo, Ferarri, etc.) and pay close attention to extreme detail.
