My question is has anyone pulled a full size pickup with a 35 ft gas motor home I have a 1997 Fleetwood Bounder 34V with a Ford 460 engine and my tow limit is 3500 lbs my truck is 4900 lbs.
Your probably limited by the hitch at 5k lbs. if you weigh the MH you can then figure out what you can safely tow. Since you will probably be flat towing there is virtually no tongue weight. Start with weighing it ready for a trip. If your OK for that weight then look for a hitch rated for 7k lbs.
I ain't saying it's right but came across this coming back from Colorado on I80.
