Since the hijack is full speed, I'd like to point out again that the reason most of us don't buy a truck just for a truck camper. We buy a truck that will work for us that can also haul a truck camper. Such is the case on the disputed truck. He bought his truck for other uses and uses it for truck campers, too. Seems perfectly reasonable.
What is not perfectly reasonable is assuming there is only one answer to the question of what truck we should buy or what truck camper we should buy. To be clear, most of us can point out shortcomings on anyone's choice. It is too easy to point out shortcomings!
Sure, a few people always think they have "the" answer. Guess what, until they volunteer to buy our trucks and campers and drive and camp in them, their opinions really don't matter to most of us!
