ADCO Designer cover. Good for 28' 7" to 31' 6" trailer.
When using it a couple years ago we had a flap opened to use the heater and wind got ahold of the flap and loosened and it burned a hole from the heater exhaust. Patched it up with ADCO's patch it. Includes the rest of the patch kit and everything needed. Water spout protectors, under straps. All of it. Worked great for snow/ice/rain.
Converted to tent campers and sold the trailer last year and the buyer didn't want it.
