Review on 🚐 RVMasking 2021 Upgraded 6 Layers Top Travel Trailer RV Cover: Windproof Camper Cover Up to 31' 7"-34' RV with 4 Tire Covers & Tongue Jack Cover - Protect Against Sun Exposure & Prevent Top Tearing by Anthony Shepherd

Cab space on my trailer plus 6" for a ladder in the back is 33 ft 10". (This does not count the 4 feet of the tongue). This cover fits my caravan like a glove. I have a Grand Design Imagine 3250BH. The material is high quality and not flimsy. It had spandex-like material in the bottom corners and is perfect for corners. My trailer is 11 feet 3 inches tall. I can't comment on durability, but I suspect it will last a while the way it's made. I live in the south and have a lot of mature trees so this cover definitely provides protection from leaves, pollen etc. I am very happy with the ease of installation.
