Water tank location
It seems that typically, the fresh water tank is typically located inside the Airstream, i.e., under a cabinet or gaucho. Does Airstream ever locate the water tank down in the frame like they do with the gray/black tanks? Any thoughts on the pros and cons of either location?

Not sure on vintage, but on new(er) Airstreams, the fresh tank hangs above tha axles. I know my 2003 19 footer had the tank inside, but my 25' has it above the axle. I'm not sure what size it starts at, but I'm thinking maybe units with at least 2 axles.

my '77 has the fresh water tank in the frame just forward of the axles. I always had the impression the change was made when the grey tanks were added, but I don't know that to be a fact.

In newer, larger airstreams the water tank sits above the axles. Others have said that airstreams with this configuration ride better with the tanks full - I cannot say from direct experience.
My 2006 16' airstream has the water tank under the roadside front dinette seat. These newer, smaller airstreams are nose heavy anyway (tongue weight easily goes over 15%) so having the tank up front doesn't help.
Certainly if you are doing such a complete rebuild that you can choose where to put your water tank I would suggest putting it above the axles as low as possible.

Our '66 TradeWind has 2 tanks, one under each dinette gaucho. It appears that the curbside tank was added by a PO. I have been trying to find out if that is so. Can anyone tell me for sure?

nope. it started w/ the body style change in '69. All of the 70's vintage have the same 45-gallon setup under the floor, just forward of the axles. But they didn't start adding grey tanks until '74.

The water tank in my '61 Ambassador is located on the subfloor on the streetside of the trailer, running perpendicular to the double axles. In my crude unscaled drawing below, the water tank is shaded gray, the hot water heater is next to it on the streetside, and the black tank is to the rear of the trailer under the subfloor. I don't know the size of the water tank yet, but it is a four foot long cylinder made out of metal (copper???). It seems to me that if the tank was full, there would be alot of extra weight on the streetside of the trailer.
I will have the opportunity to relocate the tank during my restoration so am looking for advice on the best place to put it.

Our '61 Flying Cloud had a 4' long cylinder tank that was aluminum. It was a pressurized system that used an air pump. When connected to city water the tank would pressurize while filling it. As the water level went down and the pressure decreased the air pump would build it back up. We found once I repaired our plumbing that the aluminum tank had developed pinholes from corrosion. The bottom of the tank would weep. We ended up installing a new poly tank and a water pump.
