Putting a cover on the RV

I used an ADCO Tyvek for years until I purchased a metal RV shed. Never had any probs but always check to make sure it is snug at every point.

Actually I think the trick is to get a cover made for the purpose, in the correct size, apply it correctly, and keep an eye on it.

I think your worst enemy is going to be chafe. Rubbing on the corners will rub right through the gelcoat leaving an unsighlty & expensive repair.

The fix is to use some old towels, folded over a few times & taped over the corners so that the tarp rubs on the towel, not your gelcoat. The towel makes for an easier turn on the corner too reducing the risk of a tear.

They are heavy and you got to be very careful installing it. Easy to step through sky lights and trip over vents etc. I used mine in the summer only. It was enough trouble that I had to really get motivated to pull it off and make a short trip.

My trailer is an old beater, so am not too concerned about looks. It did at one time have some water leaks, which I have repaired. I use a large tarp in winter, just big enough to cover the roof and hang down the sides a foot or so.

Personally I think sun is harder on rigs then snow.
We did use a good quality cloth cover, until we built an RV port.
One key is any tarp or cover, ensure NOTHING can rub, even in the highest winds. A grommet can rub through the paint, the filon, the.....
One other thought, if you use a tarp, put some spacer boards (2x4) on the roof, so air can circulate.

Speaking from experience you can buy a fabric trailer cover that lasts a few years and can easily rip if snagged or you can buy a thicker longer lasting tarp. Trick I learned is to hang milk jugs of water to keep tarp from flapping in the wind. Hang em almost to the ground. Bungee at every opportunity. We camp most of the year and found a metal canopy works best. I know that does not work for everyone. Best of luck

a giant tarp...strapped down with..100 bungee cords...we did it one year to keep leaves off....it worked for that

Been using one for more than ten years and our TT still looks new. I would not store it without one.
The trailer stays clean and it DOES NOT hold any kind of moisture or condensation in.
