The Motoraid unit is Winnebago specific. You can source one from them. In my opinion, it's a worthwhile feature, providing you with a tank of hot water for free on arrival at your campsite. Why are you looking for a complete water heater?

Reason you want to replace?

If it isn't leaking, generally everything else can be fixed..

Do you HAVE to have "motor aide"?

I can understand why those have been eliminated, any device which has the potential to mix extremely hazardous and deadly engine antifreeze with any potable (drinking water) system can pose high risks to the new company..

Not to mention, I would say that "motor aide" is not all that common in the vast majority of RVs, basically a feature specifically with motor homes (and even then perhaps in certain price levels), not in travel trailers or 5th wheels which make up more of the real RV market.

If leaking, Attwood used to sell just the aluminum shell as a replacement part for most of their products, not sure on the one with motor aide since that feature requires some sort of heat exchanger which provides isolation of the engine antifreeze and the potable water..

In reality one could buy a plate heat exchanger (the two water systems are isolated by a air gap but heat is exchanged between the two) and a couple of pumps and create their own motor aide from scratch..

I would reach out to the folks at Lichtsinn RV they probably have the best selection and knowledge outside of Winnebago itself.

Attwood tanks are aluminum, depending on the severity of the cracks any good fabrication shop that has experience with welding aluminum can weld it back together..

Motoraid is NOT Winnebago specific. Winne for years(about 1980 and on) used them as standard equipment on Class A models. BUT not Winne specific. Other OEM's optioned the Motoraid feature over the years. Unless times have changed, Atwood used to have BOTH Motoraid and standard replacement tanks. BUT, if the W/H was over 10 years old, it was best to buy a complete new W/H. The Motoraid is very simple. It is just an Aluminum hollow tube welded to the outside of the back of the Inner tank. You then connect the Engine water hoses to it. Most newer Motorhomes the water flows all the time. After doing an Internet search, it appears that Replacement tanks with Motoraid are no longer made. Winnebago has this as a P/N for a replacement tank. 145541-02-700 Tank-w/Insulation-6 Ga. But I doubt Winne has any. You need to call Winne parts in Iowa. I also could not find any NEW Atwoods with Motoraid for sale. So, you CAN use the standard replacement inner tank . You will just have to connect the 2 Heater hoses together with a nipple and clamps.

I would contact eTrailer and ask about a replacement as they do have rv parts.
Otherwise, remove the tank and get it welded where it is cracked

this is more common than people know, imagine if you are a full time rver and you decide to stop , for lunch or what ever , you have hot water from the system, it just makes things more convienent and easy , and why it was installed in the first place , personally , i like it as well as many other people
dometic should have given it better thought then simply trashing all of atwoods product line

Weld the tank. that heater is no longer made in that size and shape. The Texas deep freeze of a year ago went thru all of the stocks of the old Atwood design.

Suburban does make a Atwood compatible replacement but its a Suburban with its steel tank and I would not want one.

The heater disassembles rather easily and you only need a couple of sleeves that fit the outside of the flame tubes, They press in and easily done with a piece of large PVC pipe as a driver.

The H in the model number GHC6A-10E is what tells you it is a heat exchanger model.
