Its not all that uncommon to see a motorhome towing a vehicle. It is however uncommon to see that vehicle is a 6,000lb+ Hummer. Even more uncommon is when your tow behind is actually carrying a golf cart! Yes though its hard to see that is in fact a golf cart on the back of the Hummer. Your estimate of what kind of MPG they are getting? 4mpg? Negative 4?
Surprisingly, I didn’t find the Hummer in the TowingWorld.com Guide to towing a dinghy!
