re: Towing a vehicle with a class B/C motor home....

Unless you have a need for something different, save all kinds of headache and plan on towing a Wrangler. There's no steering wheel lock and they take 60 seconds to put the transfer case in neutral. You almost can't screw it up.

4 door Jeep is over 5K lbs so if you are a stickler for the rules, you would probably need to drop to a 2 door if you were trying to town it behind a class B. I suspect any Class C would be fine pulling a 4 door.

As someone else pointed out, you're probably going to be overweight regardless on any Class B/C if you load it up. Heck half the Class A's without tag axles are running overweight too...

My Class A stops just fine without supplemental braking on but it's a jerk move to run without a safety mechanism if the towed vehicle separated so to me this isn't optional. Legally it's required pretty much everywhere anyway.
