Im looking like crazy to find a new (used) truck. I want a 96-98 cause 96 is when they introduced the new cooling system. I talked to a GM tech and he said If im buying I should wait because the cooling upgrade is important. What do you guys think? I stop at 98 cause I cannot afford anything more. Its tough to find a good 96-98 3/4 ext. long box with a 6.5l and a 5spd. I found one, but its to far away. SHould I hold out for the upgraded cooling system?
