Iím a cover advocate.
I live in South Florida and cover my 34G with a Camco ultra guard cover. I had a Coleman pop-up years ago and the entire roof failed due to the hot South Florida sun over many years. Same thing happened to our friends. Anything, will last so much longer if itís protected from UV rays. I donít find it very hard to put my cover on my class A. Plenty of YouTube videos showing how to do it. Basically, have it rolled up and grab a corner or tie a rope to a corner and go up the ladder and then pull it up on the roof while it unwinds on the ground. Itís really not very hard. Having two people is nice but Iíve done it by myself several times Iíve had my cover for about nine months now and itís beginning to get small rips from the sun. I aggressively taped them together front and back with gorilla tape and that is holding very well for now. I think, if Iím lucky Iíll get two years out of it but it was only a few hundred dollars so when it dies Iíll look around again but Iíll probably buy another one and just plan on replacing them every couple of years or so.
