Weather cover during storage

We bought a cheap cover ($230) for our 21 foot class C six years ago. It is on yet and I see we will get another year out of it. I had hoped when we bought it that it would last the 3 years they claimed, well...we are way past that! It is a pain to put on, I go on the roof with it and get it done being careful not to trip on vents etc. The zippers that go all the way up the back corners allow you to pull it right off in the spring. You also can access the RV with the zippers. The way to keep the cover lasting is use 1 rope tied under the middle of the coach, then tie one rope all the way around the perimeter of the coach right above the bumpers and cinch it tight. If you use all their tie down points going underneath as we did our first year, every somewhat sharp corner and point will wear and rip through. They work well, but you must put it on and take it off. Not too bad with a rig of your size.

I have been considering a cover for mine also. I can park mine in back and its just slightly out of level which is ok with me as it keeps the rain water running off the opposite side of the coach door. But I get the black streaks from run off and I worry about the snow melt finding a way inside. If I could just keep the roof covered so I would not have to worry about leaks I would be happy.

Lots of really good information here. Thanks, and keep the ideas coming :)

We have a Coachmen B+ - have used an Adco cover on it past 2 winters without a problem. Key to putting it on is how you take it OFF the previous time! I've found I fold the sides up first, so it is "inside out", if you will, on the roof of the coach. Then roll it, starting from the front. To deploy, just set rolled cover on the roof, unroll over the front, drop the sides down and secure. I can do it alone, either just using the attached roof ladder, or a separate 10' step ladder. For my 25' coach the weight really isn't too bad to handle. And yes, mine has 3 vertical zippers on the curb side, so I can access the front cab door, the side coach door, or even the rear side compartment. As stated earlier, you cannot deploy the slide with the cover on. As far as the A/C, skylights/vents on the roof - it just lays right over them all winter. So far it has done a nice job keeping the rig clean. ST

I cover my TT that's about the same size as yours 22 x 7.5 feet plus back bumper and tongue and highest point 10 feet, the AC. With my extension ladder and working slowly I can do it alone without getting on the roof. Yes, I can access my TT's door but can't use the slide. TT two years old and shines like new. Cover lasted two years...just replaced.

I have a cover. It's made with Sunbrella. Same as a boat top. Bought it in 2006. Still works well. Thread that was used to sew it together are starting to go bad. But our 13 year old MH looks like new.
Getting cover on can be a problem. I have a tractor with a front end loader to lift the 75 lbs cover to top rear of MH. Then pull the cover toward front of MH. With cover centered on roof start spreading out sides toward edge of roof. Start dropping sides down from front to rear of MH. I work towards MH ladder. Then start climbing down ladder while pulling rear of cover down. When top is in place. Install bungee straps in the 15 sets of grommet holes. This ties cover down so it will not billow or move around when wind blows.
I got my cover from Calmark. It was more than twice what the ADCO and similar covers cost.
Here is a picture of it installed.

Friend of mine bought a named brand cover for his 38 ft 5thw 2 yrs ago. Did not last the summer here in Yuma. Tore all to heck in the wind. Took 4 guys to put cover on the 5th w. They said never again would they have a cover. I have a 40 ft enclosed metal cover for my TT

When we got our first motor home, I was going to build a garage to keep it in, but my banker said NO. in his opinion there was no need for an expensive garage to shelter a motor home that should not ever be there. His thought, and we agreed, was to use the cost to buy gas, and not need a shelter at home. Keep it out on the road! So we have!

I am not a fan of covers. If they have any play, they can flap in the breeze, abrading the surface of the rig. Instead, if one has the ability, get a pole barn or aluminum building... heck, even a ShelterLogic tent garage.

Plus, if you make the garage bigger than the rig, you have additional storage for seasonal items like Buddy heaters.

Personally I can't stand RV covers. They are very tough to work with. A job to get on and off... It will definitely require roof access.

With that said, I do believe one of the best things and RV owner should buy BEFORE they buy a coach is a metal building to keep it in. It doesn't need to be fancy or anything. Keep these things out of the elements and they can often last a lifetime. I've even seen tires go 12+ years when stored indoors.

Anyway to answer your question, covers are tough but they do work. You need to make them impeccably tight.
