I was out in my camper the other day and noticed that the water out of the hot water tap had a real rotten egg smell. I believe this is not that unusual when a water heater sits without heat and unused for a period of time. I found instructions in my manual but found them to be most curious and a little confusing. Step one says to pour in a solution of vinegar and water at a ratio of 4:2. ??????????????? isn't that the same as 2:1. Maybe that is new math or something. The question is... how much? 4 gallons of vinegar and 2 gallons of water? 4cc and 2 cc's? The second step leaves me clueless all together.
I did not add the solution of acid but I did flush the tank and got a lot of crud out initially and then little white flakes of scale from the tank upon flushing. The odor is gone for now but have a sneaking suspicion it will be back.

I have experienced the stinky hot water syndrome. I simply flushed the tank. After that, I would drain the tank if i knew I wouldn't be using in for a month or more.
Does your water heater have a sacrificial anode? You might give it a look and see if it is still there, they do have to be replaced periodically.
From my experience I would say John's advise is 100% correct. The only thing I might add is to place a note somewhere in plain sight to remind yourself to refill the heater tank before you turn the power back on. I hope you get the smell out.

When I had campers, a simple flushing always worked fine to rid the smell. Vinegar helps dissolve the built up mineral too though, so a good thing to do once a year.
Ours is an Atwood 6 gallon. The parts list has no reference to a sacrificial anode and the only openings on the back are the two water connections and the connections for the circulation from the engine.

Well, I have been reading some more and found that Atwood heaters have aluminum tanks and do not use an anode while the Suburban heaters have steel tanks and utilize an anode.

Keep it flushed out on a regular basis Phil. We drain our hot water tank and the fresh water tank after every trip and start with fresh water each time. Never had a hint of smell in the hot water system. Dave.

It really makes the aluminum tank stink if you turn on the power with out water.Ask my wife how we know that. Ron
