Ok...for anyone still heating water in your RV with propane, GET THIS. I installed this in our travel trailer earlier this year & we've been on 3 camping trips so far. We have yet to use propane to heat our water. This does a great job heating the water & it's not as slow as some people may say. Yeah, the kit is not cheap, but neither is propane. This will pay for itself in very fast. I also installed an external 120v receptacle on the travel trailer so I can then plug the electric water heater directly into the power panel at the campground instead of one the outlets inside of the camper, that way I'm not adding an extra load to the main power to the camper. Overall this was an easy install, the only issue I had was a propane line that needed to be slightly adjusted to clear the heating element. Otherwise it went well & has been working wonderfully. I definitely recommend getting this for your RV.
