It seems some time ago somebody posted Lengths, widths,weights alond with floor plan adjustments. Such as mid bath was lighter than rear bath ect. I dont remeber if I book marked it though
Well I already know that first thought is not right. I have seen a '65 manual for a 17' at 7' wide and a '66 manual for a 26' that shows 8' wide. So the search continues
Caravels were generally 6" narrower than comparable Airstreams of the same year. All Argosy Minuets were 6" narrower than standard Airstream and Argosy products of the same years.
The wider bodies didn't start until fairly recently, and it didn't make a difference how short a trailer was, it was the same width up till that point. The wide bodies are 25' and longer in the newer trailers only.
At some point wide bodies came in that increased width to legal max 8'-6"
for lengths 25' and up.
I think it was mid-90's.
Also, 8' was the maximum allowed width for trucks and trailers, except buses, which were allowed 8'6". I don't know when the law changed, but it was after 1985.
