Owning a 1994 Toyota pickup, this truck has been argued as one of the toughest trucks ever made. However, they rust. Badly.

It's usually the frame, starting from the inside where it collects dirt and water absorbs into it where it won't evaporate and will stay in there damp for months.

Cutting and welding patches onto a frame isn't the biggest deal, and you can install drain holes with places to spray cavity wax coatings.

Once it's rusty inside, you're gonna have a battle. It really needs to be coated from day and then maintained.
