The fact that you can't find pictures could be a government conspiracy...
Or it could simply be that a BRAND NEW truck that JUST HIT THE MARKET has not been used to haul a truck camper yet, at least not by someone from the "hey look at me" social media generation/crowd. It's not like Kodiaks or any other MDT were a real popular choice for truck campers. The F450 and Ram 4500 are proportioned like pickup trucks, so they can be placed under campers without cabover height concerns or overall height concerns, so they are a much more popular "more than a one ton dually" choice. Especially the F450 pickup version.
