Keep your travel trailer storage-ready and showroom-fresh with ADCO's Designer Series SFS AquaShed cover. Engineered for moderate climates and short-term storage, this cover uses a triple-layer breathable top panel to bead water on contact while still letting moisture vapor escape -- the combination that actually prevents mold and mildew rather than trapping it.
Standard tarps and single-layer covers trap condensation against your trailer's sidewalls, creating exactly the conditions that cause oxidation, mildew, and delamination. ADCO's SFS AquaShed material takes a different approach: a micro-porous film laminated between polypropylene layers repels liquid water from the outside while allowing water vapor to pass outward from the inside. The result is a cover that sheds rain and dew while your trailer breathes.
The 01-0235 is sized for travel trailers measuring 18'1" to 20' from the longest two points -- bumper to front cap, excluding the hitch. The cover itself measures 243" L x 100" W x 90" H, giving you generous coverage over standard travel trailer profiles in that size range. At just under 24 lbs, it is manageable for a one- or two-person installation.
30% more SFS AquaShed material vs. previous generation. Micro-porous film sheds rain and beads water on contact while maintaining full breathability.
Triple-layer polypropylene side panels allow moisture vapor to escape, preventing the trapped-humidity conditions that cause mold, mildew, and fabric deterioration.
Front and rear buckle cinching removes slack and keeps the cover snug. Bottom-mounted strap and buckle system prevents the cover from lifting or shifting in wind.
Entry zipper panels let you access the trailer's door, storage bays, or hookups without removing the entire cover -- a practical feature for seasonal storage.
Standard polypropylene covers are breathable but absorb and hold surface moisture. SFS AquaShed adds a micro-porous film layer that actively repels liquid water at the surface while preserving vapor transmission. That means less standing moisture against your roof seams and sidewall graphics -- a meaningful difference in rainy or high-humidity storage environments.
Cover fit accuracy starts with measuring correctly. ADCO's sizing method: measure from the rearmost point of your trailer (bumper, spare tire carrier, or ladder -- whichever sticks out furthest) to the front cap. Do NOT include the hitch or coupler in your measurement. If your result is between 18'1" and 20', this is your cover. Trailers at exactly 18' or shorter should step down to the next smaller ADCO size.
This cover's 90" height rating is calculated for a standard travel trailer roofline without large roof-mounted air conditioners or slide toppers adding significant height. If your trailer has a tall A/C shroud or an add-on roof rack, measure total height before ordering. ADCO's Designer Series covers are not designed to tent over protruding A/C units.
ADCO's Designer Series is engineered for moderate climates -- think Southeast, Mid-Atlantic, Pacific Northwest, and similar regions with regular rainfall but without extreme UV exposure or sustained high winds. For full-time outdoor storage in desert Southwest UV conditions or high-wind areas, ADCO recommends stepping up to their SFS AquaShed Plus or Tyvek-based covers. This cover is also well-suited to seasonal storage (spring/fall) in climates that see harder winters.
