I appreciate everyone telling me that basically my wife needs to "tough it out" and deal with navy showers, but I'm saying that if that's the case we are not going on any trips and we are selling the RV. My wife isn't the "roughing it" kind of woman, she has long hair and takes time with her appearance. One of the reasons we got a motor home instead of a trailer is that it makes the trip easier. I don't view installing a tankless system as being a big problem, if it makes her ok with the RV then it is well worth it. That being said, I will investigate that the system is working properly before switching over. I shower just fine without shutting hot water off at all!
