Thanks to everyone for chiming in. Oak it is!
Shari, Maxwell is simply stunning! I stumbled across an article featuring him (long before I ever found this website) and fell in love. Thanks for sharing your passion and talent.
Somehow, (I'm not really sure how it happened) we wound up taking more out of the airstream than I ever dreamed we would. I read a post once where someone mentioned awaking from a stupor to find they gutted their airstream. I guess maybe that's what happened to us....
But, we're well on our way to fixing the few soft-spots we found in the floor. The cabinets will be easier to work with since they're no longer attached to anything, right? The awful brick patterned contact paper that was stuck to the wall behind the galley came off easier if I didn't have to lean over, well, a stove. I can easily rip out the gorgeous (NOT!) contact paper in the pantry shelves. After all, they're not attached to anything anymore.
I read something on this forum once that I'll never forget (besides the hint one member gave to another member about checking Craigslist for Airstreams. That brought us to Felix): he (or she) wrote upon learning of an AS purchase by another member "congratulations! You just put a downpayment on what will someday be a nice trailer....."
How true it is!
