Hot Water Tank Replacement

Originally posted by mjlrpod I would think that if you use more than 6 gallons of hot water taking a shower, your going to over fill your grey tanks very quickly. If you take a " commando" shower as meant, 6 gallons is plenty.

You can get a propane powered tankless water heater that replaces the 6 gal tank one you have. But if you’re thinking you want an electric one so you can run it on shore power then you’d need to do some electrical work so you could run it on a 50A 240V receptacle. The 30A 120V you have in the rpod isn’t going to be enough, tankless water heaters need a ton of electricity.

If you want to get a propane one then maybe take a look at the Suburban one, it’s supposed to be a direct replacement for the one you have.

Fresh, gray, and black tanks are 30 gal, its in the specs. The "36 gallons" fresh water capacity is marketing misdirection because they're counting the water in the water heater, which can't be accessed (unless you drain it in an emergency).    

30 usable gallons, the 6 in the water heater aren't accessible unless you remove the anode.

I did alot of research on hot water heaters, maybe two years worth (I was a researcher by career, even before there was an internet).  Spoke to owners of hot water heaters.  Even before Truma came out I was told not to buy one.  But once Truma came to the US (they are German made) everyone got onboard Truma.  So maybe calling the rest junk is too much hyperbole, but if you go the tankless route there really is a huge difference in qualit.  Truma costs more but it is well worth it
