Keep your Coleman Mach III rooftop AC unit clean, draft-free, and UV-protected during storage or the off-season. ADCO's heavy-duty jersey-backed vinyl cover slips on quickly, cinches snug with a parachute-style drawcord, and holds up to whatever the weather throws at it -- season after season.
Rooftop air conditioners take a beating from UV exposure, windblown debris, bird droppings, and seasonal temperature swings. Leaving your Coleman Mach III uncovered accelerates weathering on the shroud, clogs the fins with leaves and dirt, and allows cold drafts to enter the coach during storage. The ADCO 08-0604 is cut specifically to the Coleman Mach III footprint -- 43.75" long by 29" wide by 14" deep -- so there's no excess material flapping in the wind and no stressed seams from an oversized generic cover.
The cover weighs just 3 lbs, making it easy to carry up to the roof and equally easy to remove in the spring. Polar White color reflects sunlight and blends cleanly with most white RV rooflines.
Heavy-duty vinyl with a soft jersey backing resists tearing, holds its shape in wind, and won't scratch or scuff the AC shroud surface underneath.
Runs the full perimeter of the cover base. Cinch it tight for a secure, rattle-free fit that won't shift at highway speeds or in gusty campsite conditions.
Non-tearable, weatherproof seam construction keeps water and wind out at every edge -- no gaps, no leaking seams after repeated wash and dry cycles.
Polar White vinyl resists UV degradation, helping the cover stay flexible and intact across multiple storage seasons without cracking or fading badly.
This cover is designed for the Coleman Mach III rooftop air conditioner series. The 43.75" x 29" x 14" footprint matches the Mach III shroud dimensions closely. If you own a different Coleman Mach model (Mach 1, Mach 8, Mach 15) or a different brand such as Dometic, Carrier, or Penguin, verify the shroud dimensions against this cover before ordering -- ADCO makes separate covers for those units.
ADCO has been manufacturing RV protective covers since 1968. Their AC cover line uses the same materials and construction principles as their full RV storage covers -- quality vinyl, reinforced seams, and cinch systems designed to survive real outdoor conditions. The 08-0604 includes a limited 3-year manufacturer warranty, which is one of the stronger coverage periods in the AC cover category.
