I've seen quite a few posts dealing with how to take the toppers off and on. I keep getting stuck trying to do it by myself and have come up with a way to do it that can work anywhere. Removal: Take out all bolts and leave tailgate up. Get in the back and lift slightly to break seal and start to slide off the rear. Get out and go to the rear of the topper. Pull the topper rearward until it's well past half way. You will be supporting most of the weight, with only about a foot or two still touching the K5. Slowly let your end down entil it rests on the ground. Try not to let the topper slide, just pivot at the end of the bed. Have a piece of 2x4 or whatever about 5' tall. Crawl underneith the topper, push it slightly away from the K5 and prop up with the 2x4. Pull the K5 away, go back and take out the 2x4. (Actually, I do this in the yard and leave it in nuetral, then I just push the K5 forward while holding up the topper.) Installation: With the topper propped up with the 2x4 slowly back up until you're as close as possible. Remove 2x4 and rest topper on end of bed. Go to back of topper and lift. Then carefully slide forward and re-install bolts. I have a '73K5 that is missing some of the seal hardware where the tailgate and bed rails come together. This makes it a little easier because there is nothing in the way. On the newer one, you will have to be more careful, but it can be done. Mud is just thick water, or is it that water is just thin mud?
