Not to rain on the parade here, but...
93-97 model. That is old. minimal becomes major at that point when you start dealing with wiring. Wiring in the dash can mess up your world, engine harness wiring can mess up your world.
If a truck at that age was running flawlessly, it would be ran by somebody who has owned it for a while. you have a razor slim chance of getting a truck like that from somebody that has it in perfect condition and is retiring. Even then, it's gonna cause you problems.
You are transitioning from company driver to owner operator. A breakdown that results in a late delivery can be very costly.
You have to be very mechanically inclined to take on something like that, and you have to go through it with a fine toothed comb before you put it in service, especially with today's regulations. If you find a company that will lease it on, they are likely a company you don't want to mess with. Get your own authority, and that truck could have you paying insurance premiums that would break your bank quickly.
