Aren't new tanks $800 each. I know someone that just paid $1,100 plus tax to get both his tanks cut apart, blasted, welded, coated inside, and painted. Painting the outside Doesn't help with condensation on the inside. Plastic would be great. Plastic tanks have been in service for decades. Bob Dunahugh
 
True dat. However plastic tanks are molded.
You would need to make a mold - perhaps from an old tank - because our tanks are one - off. Likely they'd have to be molded in two halves to get the
slosh baffles in them. Perhaps there's a way to make a fiberglass tank which is fuel proof? It would be a lot cheaper unless the molder could sell
several hundred of them.

And would need DOT cert which might be expensive. I wonder if any Caddy, Suburban, SOB, farm implement Tanks would work?

The problem is how shallow they have to be to fit inside the frame. There's really no better safe place than where they are. I believe someone added
a third tank, I don't know thw dimensions or capacity or plumbing.

Chuck Garton added a third tank a few years ago. He added a standard 25 gallon GMC tank by moving a crossmember and MO tying it forward. The third tank was just in front of the aux tank.
I believe there is a write up on the GMCWS web site.

The depth of those tanks is real close, but you would need to install 2 pair.

OK, Left main then right main then left auxiliary and finally right auxiliary.
Or just leave on of them dedicated to the APU.

The depths of which tanks?
I didn’t see a previous on the GMNnet referring to those tanks. Which tanks are they and what is the depth?

Daniel,
There have been a number of fabricated tanks that have been available for the coach. Yours are the best that I have seen and the quality of workmanship is noticeable. The others produced in the US have been produced using light gage mild steel sheet to keep costs down. Aluminum is a great choice, but has gotten very pricey on this side of the pond.

If there is somebody in the area of this manufacturer (Idaho) that has access to a defunct GMC MH tank, perhaps he/she could take it to this company to see if they can duplicate it!

I have sent the following to the manufacturer. Maybe I will receive a reply!

Mac in OKC

Sent Message:

"There is a considerable market for replacement fuel tanks for the 1973-1978 GMC motorhomes. These are relatively flat and somewhat squarish tanks that are maybe 6" deep and baffled to reduce fuel shift. I suspect that someone in your geographical region could provide a rusty one that could be cut up and a pattern made. Of the original approximately 13,000 of those that were built, the whereabouts of over 8,000 of them are known and probably well over 1,000 are currently on the road. More could be put on the road if replacement fuel tanks were available."

Mac,

They are not far from the GMCMI rally in AMANA. They are NE of Cedar Rapids. Between Cedar Rapids and Dubuque,IA.

After asking, Hekim told me, he payed about €800 ... for that Alutank, handmade (Euro)
He could also have had it made of Stainless,.
Making this choice I think was not bad, since shipping them to Europe will be also very costly.
And it became some bigger so, in combination with a Liquid gas installation, it is more then enough.
