2015 Dodge 3/4 Ton Really Not Camper Compatible?

Than we are mixing paper ratings, done for tax purpose with real vehicle capacity.
I wrote it few times already that my F250 short bed flatbed was carrying 4200lb of gravel just fine.
The 7.3 l engine on it was 900lb and I think that was for short block.
But it was all about making load center of gravity close behind the cabin.
Not possible with TC.
