I have a 1990 GMC 1/2 ton pickup 6" lift with 33x12.5's on it and want to know if I ask a guy I know to trade for his truck and 1500 bucks. Is this a good deal? My truck is worth more according to the banks, which is why I want the 1500 with it. HIs truck is an 87 K-5. The K5 has 145,000 miles on it, with 15k on the motor and 10k on the front end. mild areas of surface rust on rockers and one silver-dollar sized spot on door and by rear bumper. K-5 decal missing on one side. The GMC has 190,000 miles on it. Both are daily drivers and have been for their entire "lives."
