If you can do ALL the work yourself, then restoring or refurbishing a vintage may be an option.
Restore = major repairs to running gear, frame, flooring, replacing appliances (air conditioners, refrigerators, converters, axles, furnaces, etc.)
Refurbish = Lots of deep cleaning, replacing drapes, upholstery, new tires, batteries, etc.
A restoration will cost $5,000 to $10,000 in addition to your purchase price depending on what you must repair and/or replace.
My '76 Safari cost about $5,000 in parts and hundreds of man hours over and above the purchase price.
My '76 Sovereign
about $4,000 in parts and many hundreds of man hours.
I quit my job and was able to do all the labor myself.
I did not recoup any of my investment in the '76 Safari. It's market value when I finished was the same as what I paid for it.
I recouped parts from my '76 Sovereign
but no labor.
What I am saying is that it is a decision not to be taken lightly. My new 2000 Safari was nearly carefree as is our present 2007 Airstream. We spend more time camping and enjoying our non-vintage Airstream.
