These are are the numbers we're talking about.
Dry Weight10,338 lbs.
Payload Capacity3,597 lbs.
GVWR13,935 lbs.
Hitch Weight1,935 lbs.
The actual pin weight (hitch) of this unit will be approximately 20-25% of the GVWR of 13,935 or about 3,500 pounds. To this number you will need to add the weight of your fifth wheel hitch (200#), you and your SO and any pets (400#) plus any miscellaneous items you carry or have added on to the truck. You will need a one ton truck (F350, Ram 3500 GM3500) with a cargo capacity in excess of 4,100#.
These are real numbers, I've been doing this a long time. There are literally dozens and dozens of members on this site that are sharper than me and they will all come up with the same numbers, give or take.
I might also add that there are dozens and dozens of members on this forum towing 17K RV's with their 3/4 ton 'beasts.' The salesman and their friends told them 'That beast will haul anything.' Salesmen and friends always are the go-to source of good info....uh huh.
Also, you do NOT need a commercial license to drive an F350/450, or any of the 3500's of Dodge or GM in ANY state. Towing maybe another question if the weights exceed 26K.
