The idea of propane-free hot water when camping at serviced sites is appealing, and if I were buying a new water heater I would get the electric option. Having said that, retrofitting such a heater has some possible consequences, and I suggest researching them carefully. We had at least one thread discussing this issue, but I can't find it at the moment - perhaps it was almost a year ago, and lost in last year's hacker attack on the forum? I think both Atwood and Suburban have warnings posted on their websites.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.
