Sorry about the math, I was reading the original price as 6400 and you got him down 200.
Even so, patch panels can be put in badly, rust not all removed, lots of ways to mess up a paint job that you can't find out until it gets worse.
I'd really like to have another 1 ton pickup myself one day, and from what you've described of this one so far I'd pass on it at almost any price. Worth a look and something to learn from, but likely not the right truck. Unknown body work can turn out real bad.
Much better finding a known very good one and paying for it, or a very good unrestored one and doing the work or having it done. Replacing rust either cost you lots of time and sweat or lots of money to do right.
