I recently bought a '78 K5 with a four wheel pop-up camper. I've decided to throw a little money at it, thinking of starting with the tired old springs. I don't (yet) plan to do serious off road duty, just rough enough to get away from the escalade-driving masses. I don't want to have to mess with the steering or brake lines either, so I think that means don't jack it up more than a couple of inches, right? The camper weighs about 650 lbs, maybe less, it that's relevant. Any suggestions from the hardened off-road veterans for a quality spring set-up for a good price?
