I am currently debating the purchase of a 1982 GMC dually - single cab, (don't recall if it's a swb or lwb) with a rebuilt 6.2L diesel The truck is quite clean (engine compartment cleaner than some 1997/1998 trucks I've seen. Everything works, and I didn't notice any rust on upon my first inspection. I will be using it as a daily driver (I commute about 200 miles round trip a day) I was wondering if anyone knew if the gas mileage would be decent and any general opinions on the package. I have a few pics if you want to see it. They are asking $4000 for it, but I going to see if they will take $3000 cash for it, and call it a day.
