Adco Olefin Installed

Summer is over, and you're worried about your Class A motorhome getting dirty and damaged in storage during high winds, snow flurries, and spring thunderstorms. Whether you're storing your RV in the sunny south, rainy northwest, or snowy north, this heavy-duty cover is designed to protect your RV in any climate. When you keep your RV covered during the winter, you are less likely to need to wash and wax it at the start of the camping season. And if you want to trade your RV in for a newer model later down the road, this cover will help maintain that resale value.


The durable, high-density Olefin top panel won't crack or fade when exposed to harmful UV rays and won't let dirt and dust particles cake onto the surface of your RV. It also beads water when it rains to eliminate the black streaks and corrosion you tend to see on the sides and roof of your RV.


How to Measure Your Class A Motorhome


Adco How to Measure Class A RV

To determine if this cover will work for you, measure the overall length of your RV from the front bumper to the rear bumper, making sure you're accounting for any spare tire carriers and ladders on the back. Then measure the overall height from the bottom of the RV chassis to the top of the roof. Do not include any AC units, vents, or antennas in your height measurement, as the cover is already designed to accommodate them.


Securing the Cover onto Your RV


Adco Olefin Secured with Integrated Straps

The included ladder cap and rain gutter covers help prevent the cover from splitting on those areas of the RV, so install those first. Then unroll the cover and carefully spread it evenly around your motorhome, making sure you don't pull too hard and tear the fabric. The cover is labeled with "front" and "rear" to help you position the cover correctly on your RV.


Once the cover is in place, pull on the cinch ropes on the front and the rear until the cover fits snugly around the contours of your rig. These ropes remove any excess slack in the material, especially if your RV is slightly shorter in length. Then toss the weighted straps underneath your RV to the other side and buckle them together. These straps keep the cover secure on your RV, preventing it from flapping in the wind and damaging the paint job.


Adco Olefin Zippered Access Door

And if you still need to winterize or access one of the cargo compartments, you can use the zippered panels on the passenger's side to easily access the interior of your RV without having to completely remove the cover.
