It's always interesting to see how other people proceed with their projects -- I'm neck deep into what has amounted to a pretty complete rebuild of a '91 Granby, so it will be interesting to see what you do with yours.
Merrigahn's Arizona RoadRunner (Flowing Wells, just south of Wetmore) is an old-school RV repair place with lots of seemingly random bits that everyone needs - sort of like an Ace Hardware for RV's, except not nearly as organized. I've spent a bit of $$$ there (they made the new siding for mine) - nice folks.
Pancho's Upholstery (Stone & Ft Lowell) came to me highly recommended. Nice guys, but a bit slow on my new seats - maybe they're busy, or someone is on vacation, or something - who knows. I've also used Kwik Trim on 29th (east of Alvernon) in the past - they were pretty good too, but I've heard of them simply turning down work for what ever reason.
Anyway, congrats on the new project!
