We just completed the majority of the interior renovations to our 1974 Airstream Tradewind (I'm the original poster to this thread so look back to see before pictures).
Here are some of the highlights...
Completely updated layout
240v throughout for power - including uninterruptible power supply (we get a lot of trees falling over power lines up here in the hills).
lighting including LED strip lights recessed behind a panel in the ceiling.
All new upholstery
2-pak high gloss desk
(Replica) Eames soft cushion executive chair.
Dinette that converts into a kids bed
Couch that converts into a double bed (retained and modified from original)
And, pictures because I know how much you guys love pictures...
