Hi Patricia,

To keep your 2022 Thor Quantum LC25 Motorhome covered this winter, I suggest using the Classic Accessories ProTop4 RV Cover for Class C Motorhomes part # CA54NY. From what info I could find, if your motorhome is stock the 26' long cover will be perfect for it. If you've added any permanent aftermarket additions like a hitch mounted cargo spare tire that you want to stay on the motorhome during storage you may want to measure how far they stick out in case it exceeds the cover's 26' length. If it's past 26' you'd need the longer 29' ProTop4 RV Cover part # CA34NY.

The ProTop4 is a superior cover to the Classic Accessories PolyPro III part # 052963793635 you were considering because the ProTop4 has thick, extra strength fabric to repel water/snow/dirt and reinforced corners to prevent any tearing (along with foam inserts). The tension panels on the sides are adjustable as well and work with the elasticized hem to help the cover fit snuggly.

How long do you usually keep your motorhome in storage for?

We plan to store our motorhome outside at home throughout the winter, approximately November through March. We're in western Ohio, so we get snow, freezing rain, and some pretty windy weather. Our Thor Quantum LC25 is 25'2" long, 8'3" wide, and 11'2" high, measured from the ground to the top of the rooftop air conditioner. We don't have a rear ladder or anything extending beyond the rear bumper. Can you confirm that the ProTop4 CA54NY will accommodate the height of our motorhome, including the rooftop air conditioner? Also, would you recommend this cover for several consecutive months of outdoor winter storage? Thanks! Pat

@PatriciaT The ProTop4 RV Cover part # CA54NY is 312" long x 105" wide x 122" tall (26' long x 8.75' wide x 10.2' tall), RV cover manufacturers measure the height of the cover starting from the base of the RV frame down to the lower trim, so they don't include the ground clearance or tires in their fitment which explains your height difference but still confirms that this cover is a fit for your motorhome. As for the weather, the ProTop4 is specifically designed to handle winter weather. It has an extra strength 4-layer roof fabric designed to repel snow, ice, and freezing rain. The integrated air vent system in addition to the quick drying fabric helps moisture escae and prevents mold or mildew from growing when the snow/ice thaws. The cover has adjustable front and rear panels and has undercarriage click to close straps that'll keep it secure to the motorhome, so it won't fly off in the wind.
