I have just completed a little maintenance on my roof lifting system. Make sure you pump about 10-15 squirts of grease into the zirk fittings in the cable housing underneath your trailer. I also sprayed some chain lube on the cable directly.
Now, this next part is still experimental. When my roof was up, I cleaned all the supports and noted where the wear marks were. Took an eye dropper and applied a product call ZMAX on the wear areas. Supposed to "bond with metal". Lol. It is some really slick stuff so I am giving it a try. I've only raised and lowered it once since applying but it seemed a lot smoother. Going to get a travel sized spray bottle and re apply it again this weekend while camping.
