[A/S] Help! Want larger Airstream!

[Alice Boyle <alicedboyle@xxxxxxxxx>]

I'm new to this group and have never posted before so
hope this works.
My husband and I are about to embark on an arts
project with a custom designed modular/mobile gallery
which has a corrugated aluminum exterior. We want to
live on site with the gallery which is why we want an
Airstream (or another silver sided travel trailer). Of
course, we thought first of an Airstream though have
recently seen some amazing vintage trailers by other
manufacturers in our quest.
We are really on a budget so it will need to be older
and, as we will be living in it for 3 1/2 month
stretches per site, it needs to be as big as possible.
We do not have a tow vehicle so will have to hire
someone to take it to the site.
We are hoping to find one as close to our first site
in San Antonio as possible. We just missed out on one
in NC, our home state.
Any leads would be greatly appreciated.
Many thanks,
Alice
