I've almost got this towing thing down. One more ?

Note: We're never going to travel with water in the tanks. We're not using a generator. And, we're only going to need, maybe, one propane tank. That seems to be a big chunk of what begins to add up for many campers.
Other than clothes, food, blankets, pillows, and, maybe, bicycles, we don't expect to add much else in the way of weight.
