10 months ago, we "knew absolutely nothing"
of the bits-&-pieces-that-are-held-together-by-a-bunch-of-rivets that we have since, affectionately named Maxwell! We had never even set foot inside an Airstream before!
The one thing we did, that has helped ALOT is find some other folks that have Airstreams. Look up on www.wbcci.org
website to find out who else is in your area. We actually found the WBCCI folks before we had our Airstream...what better way to find out about them than to hang out with folks who have them!
Most folks, especially those with the older vintage trailers are more than willing to show you the ropes!
My other advice is, take one "mini-project" at a time so you don't get overwhelmed....use the resources you do
have (like this forum & the internet), take lots of pictures and don't be afraid to ask questions!
Good luck, hopefully we will be able to help you with your progress...even if sometimes it's just a "yup, I've tried that too"
