Maybe 99% do use their truck as a "truck", or as you put it, "to impress the jones". I don't have the data to prove/disprove this. The point is that any engineering manager worth a crap knows to design any product for the widest compatibility for their own tooling and production. So why GM chose to make something so wildly different between options is baffling. This doesn't even count the aftermarket usage. It reduces SKU's, it relies on less training as there aren't process differences. Etc. My point is that it makes no sense to design the bed, especially a lower volume bed like the CPRO, to a wildly different spec. It's just poor management.
