I have an Isata 5 with this hot water heater. Yes, it works, if one is on full hookups and has no concern for water usage or waste tank capacity. I have been using the bathroom sink on low flow hot when taking a shower. It works but fills up both tanks. (I believe the bathroom sink drains to the black tank) Also, when doing dishes it requires full hot continuously which of course empties the fresh water and fills the grey tank. I have an appointment with a Truma dealer in Wisconsin to replace my Atwood on June 24th. He is asking what are the correct model/part numbers for this change.
Can somebody give me those part numbers to facilitate this change?
I guess I will just paint the door black. Sad as the paint job is terrific but it has been six months of hot water misery and can not continue.
It will be great to rid of this millstone. The rest of the experience has been great.
La Mesa in Sanford FL. Amazing service on our Charleston, the changeover to Truma was completed on time and within agreed upon price. Service writer (Dallas) kept us informed and insured we were back on the road quickly.

Does anyone know the model number for the Truma heater and if it's a direct swap for the Attwood? Will the Attwood cover work on the Truma so the paint scheme is maintained?
Truma is "sort of" a direct replacement for the Atwood. I think we shim each side 3/4" for a tighter fit. We use the AquaGo Comfort. #78101-01 Door is
77001-01. (at least in production...not sure if that is the old or new door)
The old door is a wider flange and when we have done a replacement we use this door. You can get the door black or white...we always use black and if there is a teeny bit of non-paint exposed, once you end up sealing the door it covers. I was going to have my service tech take pictures of the next one he does so we have some general instructions.

Brian, I am also interested in changing out my Atwood for a Truma. Is it the same for a 2016 Isata 3? Any information would be greatly appreciated I too am pretty fed up with the Atwood and will do whatever it takes to change it out.
The issue is pre-recall the Atwood needed a 0.5gpm flow rater. Post recall, they over compensated in my opinion and that is more like 1.5gpm.
The Truma is about 0.5gpm but has a mixing tank to accomplish this. They have tested down to 0.25, but only guaranty 0.5. They do make a "retro kit" that has the widest flange which will cover the Atwood door and you can get it in white or black. The Truma is about 3 times the cost of the Awood and I think over $1000 to have installed at a dealer.
The other option you might want to consider is the Girard. The 3rd version is out and that one is tested to 0.8gpm. Same price as the Atwood and they also make a retro kit door in white or black. They were by the other day as we were looking at their awnings. We might test one out here on a customer coach who is replacing their Atwood. I'll let you know how that one works out.

Yes...if you see my post above, it should be the same for any model year.
As a side note, I have seen Atwood offer to change out to a 6 gallon tank under warranty. We have not done one as I think the space is a little tight, but I think they are aware there is an issue.
