Okay I got a few questions here. Alright I got 2 trucks right now, my 90k5 which Im selling, and my dd a 2000 s-10 zr2. I dont want to sell the k5 but i cant really afford to have to trucks right now, and i cant aford to drive the k5 as a DD. So i was thinking of maybe getting a k30 with a diesel. Theres one close by me a 85 k30 4x4 ex military truck with 35,000miles on it, asking $2500 for it. I know my k5 like the back of my hand, so im not worry about fixing it up, but i dont know anything about diesels. If i got this truck it would be my dd and offroad truck. If i got this truck what should i look? What goes bad on the 6.2 and how hard and how much? I want this truck at last a while. What kinda of mileage could i get with 40's and the right gears. Im pretty sure it has the th400 and i would probably would want to swap in a 456 and 205. My s10 is nice but its doesnt get more than like 15 around town, and I cant take it offroading much, it only sits 3 and thats real tight, its just a smaller truck so if i could get a k30 I figure that it would get better gas mileage, i could have a lift and go offroading and its much bigger truck and i would have alot of money left over. So if i could get the k30 and getting it running, i would just sell the s10 also. What do you all think?
