Its a Ford F53 frame and their brochure says 17,000 GVWR and GCWR is 25,000 so believe up to 8000 lbs available before exceeding the GCWR, and that assumes I don't go over 17,000 with the coach. The motorhome frame is really solid, the way they added the hitch to it isn't up to the quality and strength of the motor home frame, hence would need to change the hitch and the way it is attached.

But how much weight did the final manufacturer (the coach builder) add to that frame. You have to go by the weight the coach builder says, not the chassis builder. There are motorhomes out there that are overweight when they leave the assembly line!!!
