Make sure you change the brake fluid! I bought an '85 Dodge van w/55k miles that had been sitting for a while... I forgot to change the brake fluid. After I had been driving it for two months or so I decided to take it on a shakedown run out to the mountains behind Hemmit. Right on top of the mountains I learned my mistake... change the brake fluid. At least I found out while I was going up, not going down!
I think if I were you I'd keep it, just in case your truck failed. Unless you have some other transportation that's reliable. Even if it's a little more to fix up than you want, it might be worth it just in case... All the parts should be available and cheap, and insurance isn't going to be a whole lot. If you need to you can sleep in it. If you get a job out of town it might save you a few bucks on lodging.
