Welcome. This will change your life, similar to that first human baby (as opposed to your Airstream baby).
My 1975 Sovereign thread
started in June, 2006, and I thought I might be done in a year. I'm still not done, but it has been useable, at some level, since August, 2007. It's a slow process putting on the finishing touches!
My only general recommendation is, if you're able, don't try to do it piecemeal--it's harder and takes much longer and in the end you'll wind up (if you're like me) eventually taking out the stuff you thought you'd save. This is especially true about the floor and frame. If you've got any inkling at all that you need to replace sections of the floor or need to clean and POR-15 the frame, you will actually save time and do a much better job with the shell off. (Why can't I take this advice myself?)
Have fun and post photos. Force yourself to document every step. You might bore us to death (I doubt it), but you'll be surprised how many times you'll look back to see what the heck you were thinking. Plus, it's easier to find those useful photos here in your thread, rather than among the hundreds of other photos on your computer.
