We do offer a waterproof storage cover for your 2015 Winnebago Minnie Winnie 31H motorhome, and based on my research your Class C motorhome measures 32-3/4 inches long. I highly recommend verifying that, but if so, the cover you will need is from Camco:
- Camco UltraGuard Class C/Travel Trailer Cover - 34' Long # CAM45746
The Camco # CAM45746 is for Class C motorhomes and trailers up to 34 feet long and has a triple top layer that repels water, keeping your motorhome safe from the rain.... view full answer...
