I'll be honest - there's one thing that's nagging me about this analysis, and I'm not really sure if I should stick with what I'm doing or make a change.
The special editions (Finals, but also previous editions) don't list the Advanced Safety Group, Bed Utility Group,, Trailer Tow Group, and maybe one or two other items. But the components are built into the Special Edition packages. To this point, I've only tracked what is listed on the build sheets. I kinda feel like I should list them as "included" in the special editions, as long as they've got the actual components. That might change the results for some people..
Looking for thoughts from the group on this.
