All depends what you want it for Dave. I notice its 4x4. That in itself, running or not makes it worth something. If its a complete truck, motor, trans, tcase, both axles and driveshafts, then you have something to rebuild and don't have to go scouting for more parts, just rebuild what you got, or replace with used whatever is cheapest. Next, look for the rust at the cab corners, rockers and floor pan. If its minimal to minor and you got something to work with then go for it. If those common places have bad rust, still workable, but makes the price go way down. I'd look the frame over very well too. Surface rust, no big deal. But ifs it got any cancer on the frame at all, I'd punt. Run, Don't Walk. Reason I say that, most people I have heard that say, the frame has a little rust but its repairable, by the time they tear the truck apart and see what they are dealing with, the scrap the frame. Remember ******** Mud at the other forum???
Then look over the wiring under the hood. Make sure its not been butchered up or chewed on by rats, which is common if its sat in a pasture for a long time.
I'd also want to know more about these fuel pumps. Strange they both went at the same time huh??? So does that mean its something else, or is it possible, one went bad, then a few months later the other went bad? Don't suggest that, ask questions, to make him tell you what happened, then if that's what he says, then it makes sense. Try to trip the guy up and catch him in his lies. If he has nothing to hide or lie about, he won't get tripped up. Also, see if the RPO code sticker is still in the glove box. Find out the gear ratio. I'd hope for a 3.73 or 3.42. It could have 3.08 or 2.73 also, which are not favorable. Not that big of a deal if you intend to swap 14b full float and an 8 lug front axle. It looks to be a factory Silverado truck, so if you want those bells and whistles like pw & pl, cruise, tilt etc, the **** might not work, but it can be fixed and work someday.
Its prolly worth $450 or $500. How far out is the tags on the plates? Do you have to catch those up in your starte, or can you get Non Ops for the years it wasn't registered?? Consider all that. Don't buy a cheap truck that will cost you $500 to register.
