Ok here's my 2 cents worth. I've been in aviation going on 45 years now and am pretty familiar with aluminum structures. A sand n paint will give a few years. The biggest issue is prep work. Hard to get all the seam lines and rivets clean. Fillform corrosion can be preped if not too bad. The best way is strip n paint with a good wash primer. That will last. Moisture is the coaches biggest enemy. Newell sprayed foam in the structure. And it's stuck pretty good to the skin a reskin might be a tough road. The cap is different, no foam so not to big a deal to replace a skin. You would want to check all the rivets, look for loose, missing or working (black residue) around the rivet.. Fix or replace as necessary. Hopefully you do not have corrosion from dissimilar metal. That is a tuffy.

I loved the classics also, had watermelon lights for clearance lights. http://www.raneystruckparts.com/led-cab-lights/. Now they make them in LED. this place also has some interesting headlights some LED also.

It's worth a few extra $$$ to have done correct. Good luck...
