RV LIFE Forum Hub, Wander The West
Camper Cover
I'm not sure the answer to this but I find a lot of 22-24 ft covers made for travel trailers for sale on CL.
I'm considering one for my Grandby setup that measures out at 22 feet appx.
Seems bigger covers will provide maneuverability, but can flap in the wind. I expect the lifespan of a cover...
