First thing I'd do is get a truck rated to handle the hitch weight of this trailer. The specs say 2800 pounds but the real world will be 3000 or over. What is the payload rating of your truck? I doubt there is an F-250 out there with 3000 to 3500 pounds of payload (remember, you gotta carry people and stuff and that adds to the payload). FYI my V-3600 has a scaled hitch weight of 3500 pounds.

Short bed is not the issue. What can YOUR specific truck carry? Find the sticker on the drivers door. If aftermarket additions have been made,you must account for their weight also. Gear,people,dogs,purses also count.
No expert on runn8ng the numbers,but I doubt a 250 will be satisfactory for that 5th wheel.
One person in our group picked up a new 41 ft kz toyhauler he pulls it with a 2001 f250 4x4 shortbed nitto 33s slider hitch with F550 spring Leaf inserted into spring packs each side (witch I also did) He has no issues we pull from central fla to ride royal blue tenn, and Durham town Georgia With mud toys or ft wilderness Disney with golf carts although mine is along bed 4x4 Others in our group pull with various f250, 350s lifted and stock, regardless of conditions or weather. know your setup and be comfortable with your skills All our best from FLA
