Have you checked to see if (maybe) the water heater by-pass valve(s) is not fully closed ?

Shower water shutoff

I know this is an old post, but I just read it in a search... What are you referring to from Home Depot? Is it a regular plumbing item?

If you're not familiar with a Navy Shower, this is what has to be done, to utilize a water heater that size.

Remember, we're not at home with the conveniance of a 40 gal. quick-recovery water heater. We're camping !!!!!!

Navy Shower: Rinse yourself, shut water OFF, soap and lather yourself, turm water ON and rinse yourself. Turn water OFF so the next person will have water for their shower.

that answers one of my questions: on the home unit, a 40 gal hw heater is the amt of water it can heat in an hour. so the rv is acutally tank capacity?
in the rv, i have the larger hw heater and we have not run out of hw but it is just my wife and i.

nope, i had that wrong. gal is tank capacity. apparently i saw one one time that had the same recovery and capacaty. so there isn't a difference in the way the rv hw heater and home hw heater is rated.

I also have a water heater that will run off of propane or an electric element. When I am at a CG I always use the electric heating element and it does the job quite well, why use your own propane when I can use the CG's power. I don't take showers in the TT but my wife and kids do and they say that it is great. I know they don't take long showers but they also don't get wet and shut the water off then wash and turn water back on to rinse off. It only takes about 10 min. to heat the 6 gal. tank up when I get set up on my site and I never fire the propane water tank heater at all and I always have HOT water. Just remember if you do this you have to make sure that there is water in the tank or you can burn the electric element out very quickly(30 seconds to 1 min.).
