Plumbing - hot water heaters

Hi all, progress of our total gut of 1992 AS Excella is coming along. I have referred to many forums on this site to get where we are. Ready to put all new plumbing in, but can't find a diagram or any instructions? Any suggestions?? Also, will be moving the shower over to the opposite side of toilet and sink? Again, any suggestions?? Lastly, I will have it mainly at an RV Park with hook-up to a tankless water heater necessary? Appreciate any input. Thanks Connie

I would try and find a trailer with the same floor plan to look at and take some pictures. There is a lot more going on in a trailer. For example there are two water inputs, a pressure regulator, a check valve, and a water heater bypass.

Tankless water heaters are great if you are connected to city water, but not so great if you dry camp. The beauty of the 6 gallon Atwood is the same as it’s downfall. You only get 6 gallons of hot water at a time. That makes it hard to go through 20-30 gallons of water in a single shower, which is actually pretty easy to do with a tankless system.

"I will have it mainly at an RV Park with hook-up to a tankless water heater necessary?"
No, not "necessary.
It does't make any difference if you are in a RV park or parked in the boonies. You still want a hot shower, right.
What is the "water heater" used for? a conventinal "Atwood" 6 gal water heater works 24hrs a day to keep that 6 gal warm. using propane and depending on the water quality and mineral content building up sediments and you also have the Anode to replace every so often. Pain in the rear. They are much cheaper initially.

I believe tankless is the way to go. There are a few brands to consider. We went with "Precision Temp, Twin temp JR" to both heat the trailer and heat continues hot water for hot showers all day or night long. It has been the single most used and loved upgrade we did.

Oh, By the way. We use ours dry camping almost exclusively and it works flawlessly.

Plumbing isn't that hard. Pre-fit everything and just remember what "rolls downhill", lol. One thing that might help is the type of P-trap you are using under the sinks and tub/shower. I switched over to HEPVO 1-1/2" Trap. They are a life saver for restricted spaces and have worked very well for the past 8 years. Best of luck to you.

When I replaced my water heater a few years ago I considered a tankless.
I decided to replace it with another 6 gallon Atwood.
The Atwood always provided sufficient hot water and lasted almost 20 years. I do not need "endless" hot water.
And, I like the option of using the campgrounds shore power for water heating when staying at a park with full hookups.
For me, the additional cost for a tankless WH could not be justified.
