I would forget a cover. I had one for my 27" Jamboree in '89. My experience was that it took my DW a lot of effort to get it on the roof, (I don't do heights) Once there it was not very difficult to open and put in place. I tried the lines attached to the eyelets on the cover with weights attached all around. That lasted until the first wind. The cover ended up in the cornfield across the street. Next we tied it down and across the bottom of the MH until the next wind. I then bought 750' of rope and tied that around in every direction. The next big wind took the cover again and left all of the rope still in place. We sold the cover with the MH and have had open storage until we moved to Holland amd now keep it in a barn.
