I spent alot of time searching this website for this post, and this is one of the few things I was unable to find. I had some rotten wood and it caused the top post to bend and snap. I have been working on replacing the roof sides, however today I finished one side and needed to repair the post so I can move the camper. I originally thought if you removed the springs from the bottom, you would be able to pull the posts out the bottom. I was incorrect. Slide the bed out and prop it up on the side that needs replaced with something, I used a short ladder. I used a 2x4 to hold the roof up while i completed the rest. Lower it down onto whatever you are going to use to prop it up. First removed the bolt from the top of the post There is about 10 screws on the inside of this piece. Remove them and this piece.(You can see the ladder I used to prop up the other end of the bed) This holds the rail, so make sure it won't fall after removing the screws. Also, my canvas is only down because I am working on the roof. You do NOT need to take it off to replace a bent or broken post. Take the screws out of the flat side of the last piece shown here. There is also a small corner piece that I forgot to take pictures of. Its two screws and cant be mistaken. Then you must scrape some caulking off, not alot though. I took my spring out of the bottom, which was unneccesary, that is why the telescoping post is sitting flat. I did this again without taking the spring out of the bottom, so I am sure it can be done both ways. It easily lifts out from here. there is a small piece in the bottom that pushes out and the telescoping posts slide right out after you get this piece out. I took a picture of this too, however my photobucket is deciding to not work anymore. Also please make sure that the posts are the same before putting them back. I urge you to do this, because I did not. Thats how I know you can do this both ways. My old post was 28 inches long and the new one was 23 inches long. This is actually very simple to do. I had it back together in under an hour with no guidance. I would also measure the fully extended height before you take the old one apart so you can get it set back to the same exact spot. Best of luck.
