Greg. I think you are right and the issue of an uphill or downhill tow bar causes a toad to exert an upward force if the hitch on the coach is too high, or conversely if the hitch is too low it might contribute to the toad trying to climb upward.

I agree a light toad might have little impact on our coaches, but I have seen Class C motor homes towing a vehicle like a Tahoe and they need to be as level as possible otherwise their already compromised braking is going to be very bad.
