Seems to be enough hits in your area to keep you busy for a few weekends.

Most of the mechanical issues you will come across are pretty typical for all vehicles that are 20-30 years old rigs.
Lack of maintenance, non-working electrical items (doors, windows, seats, etc.) and previous owner mod's.
Rust is fairly easy to spot on these, rear quarter panels and the frame area by gas tank/skid plate.
Most sellers won't want you pulling up the carpet below the front air vents. The cowl opening drains into the air vent area and becomes clogged with junk. This area then holds water and it will flow onto the floor by both the driver and passenger feet areas.
Poking around this area underneath with a screwdriver will usually reveal major rust through if it's that bad. There is going to be some, I've only torn down one rig that did not have at least some surface rust in those areas.
