Steel or plastic water tank?

Hello all. This is my first post.

I have an 83 airstream excella and was wondering what type of fresh water tank these have in them?

I don't want to remove some of the sheet metal underneath just to find this out. Can some one chime in on this?

Thanks

First, welcome to the forums.

Way early on, like in the 60's, the water tank was aluminum, and that was the pressurised one.

I don't know exactly when they changed, but they are plastic now, and have been for quite a while.

I believe the early pressurized water tanks were in fact galvanized steel, not aluminum.

A 1983 trailer would have a plastic tank. The switch away from steel took place in the early 1960s.

My father had a '61 31' that had a pressurized aluminum tank in it. Don't remember the year of his next Airstream, but it had a plastic tank with the demand water pump....the one with the belt, crank shaft, rod, and piston/diaphram.

Our '83 Excella has a plastic tank. It is held in place by the bolted on pan. there are no straps holding the tank.

Smile galvanized steel

Bud here; I have a galvanized steel 14''X 60'' that has a 4'' tear in it.
It has a air pump that pressure the tank to push the water up the pipes.
Can I use a plastics tank and will hold the 50/60 pounds, and change to a water pump.
Thanks 24/62 tradewind

You can use a plastic tank with a water pump. 50/60 lbs is about 6-7 gallons.
