Have a friend, girl I went to highschool with. She's selling a 94 Burb, 3/4 ton with the 454 (I think). It's got 67K original miles, and is pretty clean. The 4WD wont engage (not too worried, I figure it's probably the vacuum disconnect, or a t-case (I can get a 241 for pretty cheap) issue. The A/C pump is bad too. Other than those two things, it's pretty good. She want's $5500 for it. I want this Burb because I am starting my own business doing crime scene clean-up. I can haul my gear around in the back, and tow a flatbed or stakebed trailer to haul any debris or stuff to the disposal site. Might also be a decent towrig for the K5 in a pinch Thoughts? Advice?
