Cover
Adco also makes one that is grey in color and warranted for 2 years. Stay away from that one; it will fall apart in less than 2 years in the Florida sun. I live in Odessa, Fl. which is the West Central part of Fl. I am building a permanent carport cover for mine; a painter's tarp made out of canvas is better than a bought cover from Adco. You can get these at Lowes. Put some grommets around the edges; get some tent waterproofing spray and treat the canvas and you're all set. Sure, they will rot over time; but it is still cheaper than buying a cover and dealing with ADCO after theirs falls apart.
There area lot of sharp objects on the HiLo that will overtime poke holes in any cover when the wind is blowing. Cover these sharp edges, like the awning end caps, the antenna, rain vent edges, etc. with some soft plastic, then tape down and finally cover with your tarp.
