Full-season protection for large 5th wheels and toy haulers. The Classic Accessories Overdrive PolyPro 3 Deluxe (Part 01-0859) uses a triple-ply PolyPRO3 roof and top panels paired with single-ply PolyPRO1 sides to block rain, snow, UV rays, and road grime while still letting trapped moisture escape. Purpose-built for rigs 38 to 40 feet long with a maximum height of 124 inches from ground to roofline.
Storing a 38-to-40-foot 5th wheel or toy hauler without a cover is an invitation for UV fade, water intrusion, and surface damage. The PolyPro 3 Deluxe is designed specifically for rigs in this size class -- a category where cover fit, panel strength, and ease of installation matter most. At 44 lbs, this is a heavy-duty cover, and Classic Accessories includes a toss bag and integrated rope attachment system so you can get it positioned without crawling under the rig.
The dual-material construction is intentional: the thick triple-ply top handles the harshest exposure (sun, hail, tree debris, snow load) while the single-ply PolyPRO1 side panels stay lightweight and breathable. The result is a cover that sheds water at the top and breathes at the sides, which is exactly what prevents mildew and condensation buildup during long storage periods.
Thick three-layer fabric on the roof and top sections resists rain, snow, UV degradation, and surface abrasion season after season.
Vents built into the cover design allow interior air circulation, reducing wind stress and preventing moisture and mildew buildup inside the cover.
Full-height rear zipper for toy hauler ramp door access plus additional zippered panels let you get into your RV without removing the cover.
Adjustable front and rear tension panels combined with elasticized hem corners pull the cover snug against the rig and minimize flapping in wind.
Classic Accessories includes a toss bag with integrated rope to help you guide the cover over a tall 5th wheel from the ground. Cuts installation time significantly on a rig that can top 10 feet at the roofline.
The roof and top sections face direct sun, pooling water, and falling debris, so Classic Accessories uses PolyPRO3, a denser triple-ply material, in those zones. The side panels see less direct exposure and benefit more from breathability, so single-ply PolyPRO1 is used there. This keeps overall weight manageable (44 lbs) while putting extra protection exactly where it is needed most.
This cover is sized for rigs with a total length of 38 to 40 feet and a maximum height of 124 inches from the ground to the highest point of the roof. Measure your RV fully extended, including any front overhang or rear accessories that add to overall length. If your rig is 37 feet or under, see the smaller PolyPro 3 size options. If it exceeds 40 feet or 124 inches in height, this cover will not fit correctly.
