Buy an Avion. You can get more trailer for your money, they are insulated better and those of us that own them feel they are built better than the Airstreams. We paid $5k for our 1986 Avion 32S, you can see pictures in my thread "Avianca - the cure for alumatitis". It is more difficult to find the 30-32' as most of them were 34', but well worth the searching.
This is actually a 1988 32S which is a 32' model, easy to tell by the double axle instead of the triple axle. Pretty nice for $10,500.

You can open the storage doors along the sides of the Avion and see the outside of the frame, gives you a good idea what it would look like above the belly pan.
I know you said, must be airstream, but I liken it to the fact I don't own Yeti stuff, I own RTIC. Because I want quality, but don't need a certain name brand to feel like I got a good product.
This is our second one, wished we hadn't sold the first. If we convince ourselves to give up the 9-5 routine, sell everything and hit the road, it will be in this trailer.
Btw, love Kerrville. We are originally from central Texas, but I have family in Medina, Fredricksburg and Campwood. Spent a lot of my younger years on the Camp Ranch just up the hill and across 187 from Lost Maples.
