I have looked at these in the past and actually bought one of the "portable" versions. It worked fair at best but I would NOT install one on an RV. If your full timing and not going to move around it might save you a little butane. But if your a weekend warrior I don't think the hassle is worth the very marginal benefit. I would go with a electric/gas version since you don't pay any more for using extra electricity at most weekend campsites..... On the other hand if your looking at one for your stick and brick house then there is some benefit in that it uses a lot less gas (they only make these in a gas fired version no electric). However your going to be a long time paying out the substantial higher purchase price vs a conventional unit and good luck finding someone to work on them. Might be some value for someone who either lives off the grid and or is extremely environmentally sensitive.
