Gene,
thanks for the tip. I've hitch carried bikes for many years. If it's a long trip, they go in the funmover. I have a physics degree,and am aware of the effects of leverage. This topic does come up from time to time and people should be aware, especially in lighter vehicles. People do also need understand a 300 lbs cargo off the receiver is nowhere near as stressful to the vehicle as a 8000 lbs cargo, with 800lbs tongue weight surging up, down, left, right, in, out.
These class b vehicles are very handy for a couple days ride.
