Not towing a car, MH hitch only rated for 3500. not sure how people tow race cars with these things. Anyways, hitch has bike rack with 2 electric bikes for short running around. Empty container is safer than full, but you don't have to buy a can when you get to the station. Have to remember built in generator won't work if gas is below 1/4 tank anyways. Probably over thinking this and over packing as usual. Worst feeling is something happens and I wish I had some tool/(whatever) that I could have brought to fix the issue. We are planning on hitting all the major parks in the southwest, not sure how densely populated those areas are, wasn't too thrilled paying $4 a gallon along PCH last winter.
