Purpose-built for large fifth wheel trailers, the Gold Shield 5L delivers heavy-duty all-season protection through a 5-ply top and 3-ply sides -- blocking sun, rain, snow, hail, tree sap, bird droppings, and road dust while its breathable microporous film keeps moisture from trapping underneath. At 25 lbs with zippered access panels, reflective strips, and a ladder cap included, this is a serious long-term storage cover sized for rigs from 41 to 45 feet.
Storing a 41-to-45-foot fifth wheel means exposing an enormous surface area to the elements. Cheaper single-layer covers trap condensation, fade and crack in UV, and blow loose in wind -- leaving your paint, roof sealant, and slide toppers worse off than before. The Gold Shield 5L is engineered to handle that full exposure, starting with a five-layer top panel that combines UV-resistant polypropylene with a micro-porous film core. The result is a fabric that sheds water and blocks over 98% of airborne dirt without sealing in the humidity that causes mold and rot.
The three-layer side panels extend that protection around the full perimeter, with an extended top overhang that carries coverage down the sides for additional runoff shielding. Elasticized front and rear hems conform to the corners of your trailer, while adjustable weighted buckles pull the slack out and prevent the wind billowing that causes fabric fatigue over a long storage season.
UV-resistant polypropylene outer layers with a microporous film interior block water and UV while letting water vapor escape -- no trapped condensation, no mildew.
Reinforced three-layer sides resist crosswind abrasion, side-on rain, and debris -- covering the full height of your trailer walls on both flanks.
Reach your entry door and pass-through compartments without pulling the entire cover -- essential for checking on a rig in long-term storage.
Pre-cut vents accommodate up to three rooftop air conditioning units, so the cover lays flat and secure over your full roofline without modification.
Fit is what separates a cover that protects from one that just sits on top of your rig. The 5RV-5WT-4145 is sized for trailers with an overall length of 41 to 45 feet, with a cover footprint of approximately 45.5 ft long x 8.58 ft wide x 10.08 ft tall -- giving you the overhang needed to tuck under eaves and gutters without pulling tight over corners.
The microporous film layer is the critical difference between a cover that protects your rig and one that ferments moisture against it. Water vapor from temperature swings passes outward through the film; liquid water cannot pass inward. This is especially important in climates with freeze-thaw cycles or humid shoulder seasons where condensation under a sealed cover accelerates mold, rust, and delamination.
Long-term storage puts cumulative stress on every seam and panel. CarCover addresses this with reinforced double stitching throughout the cover body and at all high-stress attachment points. The fabric itself is sun-reflective, which serves two purposes: it keeps the interior of the trailer cooler during warm-weather storage, slowing dashboard cracking and upholstery fading, and it extends the life of the cover fabric itself by reducing heat-related breakdown of the polypropylene layers.
The Gold Shield 5L is backed by a lifetime manufacturer warranty against defects in materials and workmanship. The included patch kit covers minor field damage so a small snag does not become a warranty claim or a replacement purchase.
You can wash the cover by hand or in a washing machine. For hand washing, install the cover on your RV, rinse it with a hose, then use a cloth and multi-purpose cleaner to scrub. Rinse again and either towel dry or let it air dry.
For machine washing, use the largest machine available, set it to gentle mode, and wash with mild powder detergent in cold water—avoid bleach and fabric softeners. Rinse the cover twice to remove all detergent, and always air dry.
