I'm still trying to figure out the lifting system inner workings. I saw the diagram you made of the slider tube with the little pulley at the top to anchor the cable.
Where exactly is that pulley and how big is it. I try to visualize it by following the cable tube but can't make sense yet. Also, how do you service the lifting system, do you remove the tubes thru the outside corners? I really want to figure all this out,so to be ready if the system fails. I drove a Mack truck for years and always fixed myself. Yesterday the shower tent came in, it's a 5x5 Browning type, plenty room and even a small shelf inside. The screen window unzips so I can route the shower head hose thru it and hang it on the ceiling. I bought a small kiddy inflatable pool for the bottom and two small coleman foldable benches one in and one out.
