Ditto.
I guess it kind of depends on the size of the camper you have in mind too. Some campers may not have the space to accomodate one.
I would make a horrible full timer in a truck camper, because I'd run out of water all the time. I like hot showers.
As far as how I use the water heater, I don't just turn it on and leave it run full time. I only turn it on when I need it for a shower or doing dishes. Doing dishes has been a rarity for the last few years though because all my trips have been short ones, with microwave meals and plastic forks.
