Just bought a Class C, and I'm planning on towing an '03 Jeep Wrangler. Have the base plate on, got it wired, bought a Demco tow bar, and now the issue. The RV is way low, and the jeep is way high. ...
If your Demco tow bar is like mine, it does have some amount of adjustment so that you can angle the head to somewhat compensate for the height difference. If it's really 10", that may be more than the adjustability it may be able to compensate for.
