The Classic Accessories PermaPRO Model 7 is a purpose-built storage cover for travel trailers in the 33 to 35 foot range. Extra-strength ripstop PermaPRO fabric blocks UV rays, repels water, and resists dirt and dust, while a multi-vent air system and integrated strap design make installation a one-person job -- no crawling under the rig required.
Storing a 33 to 35 foot travel trailer unprotected means slow UV degradation of your roof seals, oxidizing fiberglass, and grime that grinds into every crevice. The PermaPRO Model 7 is designed to address all of that without trapping damaging moisture underneath.
The PermaPRO fabric is a high-denier ripstop weave that resists tearing while remaining light enough for one person to handle. At 27.2 lbs for a cover sized to fit a 35-foot trailer, it is meaningfully lighter than comparable covers using heavier woven poly shells. The quick-drying surface and built-in venting system work together to prevent the greenhouse effect that causes mold and mildew under non-breathable covers.
Extra-strength ripstop construction repels water, blocks UV, and resists tears and punctures without the bulk of heavier materials.
Weighted toss bags feed the tension straps under the trailer without requiring you to crawl underneath -- a real advantage on a 33-plus foot rig.
Strategically placed zippered openings let you reach RV entry doors and exterior storage compartments without removing the cover.
Adjustable front and rear tension panels plus elasticized hem corners conform the cover to your trailer's specific profile and reduce billowing in wind.
Classic Accessories engineered the PermaPRO line specifically around the real-world challenge of covering a large trailer solo. Key features that make installation manageable:
Classic Accessories sizes PermaPRO covers by overall trailer length, measured from the front of the A-frame tongue (or nose cap) to the rear bumper. The Model 7 cover is sized for trailers measuring 33 feet to 35 feet by that overall measurement.
The cover dimensions are 426 inches long (35.5 ft), 104 inches high (8 ft 8 in), and 102 inches wide (8 ft 6 in). These generous dimensions accommodate most standard-height travel trailers in this length range, including slide-equipped units, as long as slides are retracted during storage.
