Cuse,
From your name I would guess that you are in Syracuse. I grew up there until moving to Las Vegas (NO RUST) 8 years ago. Here's my opinion FWIW. An old truck is a lot like an old friend or even a family member, especially after 15 years. If you are not confident in your sheet metal/body working skills then park it, save up some $$$ and have a professional body job done, especially if the mechanical end is still sound and you are good with that part of the work. It may cost a bundle, but once it's done, you'll have a really great truck that you can enjoy (if taken care of) for the rest of your life. If you let it go, you will kick yourself in the butt every time an old truck (cherry or beater) passes you on the road.
