It looks great! Check the front and rear top caps with a magnet. If it sticks, it is galvanized steel. You can keep it silver but you'll paint it silver instead of polishing it. You cannot polish the steel to look like the rest of unit.
Here is an Argosy that has been stripped
. You can see the front cap is different. There was an Argosy 20 in Colorado for sale just recently that was stripped to the bare aluminum and the caps were obvious.
Yes, I have a 1977 Argosy 20'. This one
is my unit.
There is no one place to get all of your stuff. There are a few places that most of us shop but it depends on what you need. The great thing about these units is that your chassis is a 1977 Chevy P-30 and you can get parts at just about any local auto parts place! It is a very common truck chassis.
I also recommend inlandrv.com
. Andy is a great resource. He really knows his stuff and he insists on doing it 150% correct.
