Hey Kevin,

The Classic Accessories PolyPro III Deluxe RV Cover part # 052963750638 is going to be your best option for covering your RV for winter. This cover is made of a polypropylene fabric that helps wick moisture away from the trailer's surface and has built-in vents to stop water from pooling or freezing and causing any corrosion or mold. It also has zippered panels on the passenger's side so you can access the inside of your trailer while it's in storage without totally removing the cover. The straps and panels will help to keep it from flapping around in the wind and tearing during any weather as well.

What kind of climate will you be storing your camper in?

Hello - We bought this cover about two years ago. We live in the PNW and Summer sun is a UV killer. This is the best RV cover we’ve ever purchased but that said, this cover like all the rest IMHO last only 3 years - Possibly less. I’d recommend buying this in a heartbeat but be prepared to buy another one in about 3 years if your RV is outside “24/7/365”. Happy trails! ??

@GregoryS That's pretty impressive to hear that this cover withstood the PNW summer for so long! UV is the biggest killer for these covers, but 3 years is a pretty good run. Do you travel with your camper during the winter and summer back in the PNW?

We've owned our 5th wheel RV for about six years now and my wife recently retired. We've had two of these covers over the course of six years, we've replaced it once. Our RV is stationary (parked) and we recently went on a 3-week RV trip to GNP (Glaicer National Park). We're driving down highway 101 in December and we'll be RVing for 2-3 months ending up in Quartzite Arizona. We don't plan to pack this RV cover during our trip but we will most certainly put the cover back on when we return to the PNW. Hope this info helps!

@Gregory Oh wow! Those are some pretty exciting trips! Montana is on my list of places I want to visit so we can see Yellowstone and Glacier National Park. Do you have any favorite places you've visited?
