Keep your 5th wheel trailer in showroom condition between trips. The ADCO Designer Series SFS Aquashed cover uses a triple-layer polypropylene construction with 30% more SFS Aquashed material on the top panel to bead water on contact, block UV rays, and maintain breathability to prevent mold and mildew buildup. Engineered for moderate climates and short-term storage.
ADCO's Designer Series has long been a go-to entry-level cover for RV owners who want real protection without overspending on features suited to extreme climates. The SFS Aquashed formula -- applied to the critical top panel where rain and UV exposure are greatest -- sheds moisture while allowing trapped humidity to escape. The result is a cover that resists the two most common causes of stored-RV damage: water intrusion and mold.
This specific cover (ADCO part 52256, SKU 01-0248) is sized for 5th wheel trailers measuring 34 feet 1 inch through 37 feet in length. The 450" x 108" x 126" footprint accommodates the tall profile typical of modern 5th wheel designs. At 39.52 lbs, two people can manage installation comfortably, especially using the included weighted tie-down assists.
The roof panel uses 30% more SFS Aquashed material versus previous generations -- beads water on contact and resists prolonged exposure to rain and high humidity.
Side panels use durable triple-layer polypropylene that blocks UV rays and resists tearing, while remaining breathable enough to prevent moisture buildup against your trailer's exterior.
Front and rear buckle cinching straps remove slack and keep the cover snug against the coach. A bottom-mounted strap and buckle system prevents billowing or loss in wind gusts during storage.
Integrated zipper access panels let you reach compartments, slide controls, power connections, or storage bays without removing the entire cover -- a real convenience during seasonal storage.
The SFS Aquashed system combines a spun-bonded outer layer, a film center, and a breathable inner scrim. This tri-layer approach sheds liquid water at the surface while vapor from condensation passes outward through the cover rather than pooling against your trailer's gel coat or painted surfaces. ADCO applies this material to the top panel, where rain load is highest. Sides use a standard triple-layer polypropylene construction that handles UV exposure and abrasion from wind movement.
ADCO rates the Designer Series SFS Aquashed for moderate climates and short-term storage. This means it performs well in regions with seasonal rain, moderate UV exposure, and occasional wind -- think the mid-Atlantic, Pacific Northwest shoulder seasons, or the Midwest outside of peak winter months.
Two people make installation significantly easier on a full-size 5th wheel. ADCO includes weighted tie-down assists specifically to solve the problem of routing straps under the coach without crawling on the ground to retrieve them. The installation sequence is straightforward:
