f250 6.2 and 327re good match or to much camper?

Open drivers door......YELLOW Sticker

It will have MAX Cargo Carrying Weight XXXX
Subtract your weight, ALL passengers weight, any stuff in cab, any stuff in truck bed including weight of 5th wheel hitch from that MAX CARGO number.

How much is left??

Is it enough to handle 20-25% OF 5TH wheel GVWR (wet pin)
10,000 Dry weight----loaded up camp ready closer to 11,500/12000
20% of 12000 ----2400# wet pin

that 5vr (327re) is going to be close depending on MAX CARGO number and trim level of truck
