Notice that Fleetwood takes a more conservative assumption. Winnebago has a 5,000 pound rated hitch but has less than that available in the net of GCWR - GVWR. Just because it says 5,000 rating doesn't mean there is enough reserve to do it.
Fleetwood commonly has a tow rating on their hitch of 3,500 lbs. my '01 on a Chevy 3500 chassis is that. 15,800/12,300. I have over 3,000 pounds cargo carrying capacity even after fresh water, LP and such are full and I still wouldn't tow something 5,000 pounds. Good rule of thumb is to not tow more than 80% of your tow capacity. I'm right at that towing an '03 Tracker
Some here may suggest that this can be solved by installing a more substantial hitch and reinforcing the frame extensions. I
looked at my frame extensions and I would not exceed the 3,500 rating as is even if
