It's not hard, but I wouldn't try it without help. The springs are where you need to really pay attention, both unloading and re-loading them. The tube replacement is relatively easy. We left the fabric attached to the coach and unrolled it, letting it hang on the side of the coach. Then we slid the tube off, the new one on, and reassembled.
