I need a course in R-Pod water Heater 1001

thanks much for the help I'll look next weekend , working doubles all week 

I'm also learning where everything is on my 175 (2010 model).  After searching for my hot water heater by-pass valves, I located them behind a small access panel in the rear storage area (left side).  4 small screws held it in.  That being found, I could not see or feel them.  I ended up crawling through the right side storage area door to see if they were even in there.  They were, and in the Summer mode (by-pass valve closed).  Possibly could also be accessed by removing mattress and plywood under it, however I didn't check this possibility.

I have been unable to get the water heater to work on LP alone and will take it in to a dealer for warranty work but first wanted to see if anyone had suggestions as to what I might try trouble shooting wise before I make the trip to a dealer. Here is what I have and have tried.

The documentation is almost worthless, yes.  A shot in the dark - on my popup there was a valve where the water heater connected to the gas line.  I don't know if they have one on the 'pod but its worth a look.

A word of advice...I don't like to leave water sit in my hot water heater when the Pod is stored between trips.  I found that my domestic water (and a few camp ground water supplies) tends to use up the magnesium anode rod quite quickly if the tank is allowed to sit full.  The used magnesium tends to form a white material in the tank which eventually clogs the sink aerator and stops up the shower nozzle.  I also don't like the idea of drinking the dissolved magnesium.
If I plan on storing the Pod for more than a few days, I open the sink faucet to relieve any existing water pressure...unscrew the anode rod and drain the water heater.  I temporarily replace the
rod with a similar diameter/thread PVC end plug (I don't want vermin to crawl into the heater tank).
WARNING...adjacent to the anode rod port, I used a permanent marking pen to write a warning on the water heater to make certain that I have shut off the 110VAC heater switch.  I plug in the Pod every so often to keep the batteries charged, and it would only take a few seconds for the dry
electric heater rod to burn itself out.  So when I remove the anode rod I see the warning to shut off the electric switch.
I carry a trip checklist and the first item is 'replace the anode rod and fill the heater tank'.
