Keep your folding pop-up camper protected through every season with the Classic Accessories PolyPRO3 Model 4 cover. Built specifically for folding pop-up campers in the 14 to 16 foot length range, this cover uses a three-layer composite fabric and an integrated air vent system to block UV rays, bird droppings, dust, dirt, and moderate rain while still letting trapped moisture escape -- so you don't climb back in spring to find mildew damage.
Pop-up campers present a unique storage challenge. Their low profile and folding roof canvas are vulnerable to UV degradation, bird droppings, and moisture accumulation far more than hard-sided units. A cover designed for a travel trailer simply won't conform to a pop-up's shape -- that's why Classic Accessories engineered the PolyPRO3 line specifically for folding campers, with tailored sizing by model number.
Model 4 is sized for pop-up campers measuring 14 to 16 feet in box length. The cover ships with a stuff sack for compact storage and a rope toss bag to help route the attachment rope under the unit without crawling on the ground. Adjustable tension panels at the front and rear, plus elasticized hem corners, pull the cover snug against the camper's profile for a secure, rattle-free fit in storage or at the campsite.
Composite construction with a polypropylene outer layer, middle membrane, and soft inner lining resists UV rays, dust, and moderate precipitation without abrading the camper's finish.
Vents built into the cover work with the quick-drying polypropylene side panels to equalize pressure, reduce wind stress, and allow interior moisture to escape during storage.
A weighted toss bag lets you route the integrated rope attachment system from one side of the camper to the other without lying on the ground -- a genuine time saver during solo setup.
Front and rear tension adjustment panels plus four elasticized hem corners conform to the specific contours of your pop-up, preventing billowing, flapping, and cover shift.
The PolyPRO3 name refers to Classic Accessories' three-layer bonded fabric system. The outer layer sheds water and blocks UV radiation that degrades canvas tent fabric, vinyl bunk ends, and plastic trim over time. The middle layer adds structural integrity and moisture resistance. The soft inner layer prevents the cover from scratching painted surfaces, gelcoat, or aluminum skin as it moves slightly in wind.
The sides of the cover use a quick-drying polypropylene panel construction that allows airflow -- this is important for a pop-up specifically because the canvas tent fabric needs to breathe during storage. Sealing a pop-up in a fully waterproof, non-breathable cover traps condensation and accelerates mold and mildew growth on the canvas. The PolyPRO3 system balances weather protection with ventilation.
This cover is engineered for the low, boxy profile of folding pop-up campers only. It is not intended for travel trailers, fifth wheels, or hard-sided tent trailers. Using it on the wrong unit type will result in poor fit and reduced protection.
Before purchasing, measure your pop-up camper's box length with the unit fully collapsed and closed. Model 4 fits campers from 14 feet to 16 feet in length. The cover's published dimensions are approximately 204 inches long, 88 inches wide, and 42 inches high -- sized to wrap a collapsed pop-up including the roof deck.
Pop-up camper length is measured as the box (hard-sided cabinet) length, not total length including the tongue and hitch. If your pop-up is near the 16 ft upper boundary, verify the width dimension fits as well. Classic Accessories offers additional models (Model 1 through Model 6) for smaller and larger pop-up campers.
Between uses, store the cover clean and dry in the included stuff sack. If the cover becomes dirty, hand wash with mild soap and cold water -- do not machine wash or use bleach, as this degrades the UV-inhibiting outer layer. Allow the cover to fully air dry before storage to prevent mildew on the cover itself.
Classic Accessories backs the PolyPRO3 Model 4 cover with a limited 3-year manufacturer warranty against defects in materials and workmanship. Warranty claims are handled directly through Classic Accessories.
