The longest single axle Airstream ever built, believe it or not, was a 30 footer, many years ago.
After that a 24 foot was tops.
Of recent vintage, 1969 and up, it was 23 feet.
However the 23 foot single axle was short lived, as Airstream changed it to a tandem axle, for a number of reasons.
A single axle 23 foot can be changed to a tandem, but only if you have the original drawings which also require some floor plan changes.
Changing the 23 fron a single axle to tandem, is not for a DIY.
Of immediate concern if your towing your trailer, is the condition of your axle.
1974 and older axles will all fail in due time, because of the incorrect composition of the rubber rods that were used then.
The following will help you to chck out your axle.
