We have had covers on all our rvs and have used several brands. To date, ADCO is my favorite and is the one we have now. Watch for them on sale. We got a discontinued color from camping world which l like better than the new color. Best thing I can say is get one that fits well as too small, Obvious, and too big will flop in the wind and can tear up your paint and roof. Make sure you pad all ladders, rain gutters, bumpers, grill mounts, and anything else that can snag and tear your cover. A few reasons why I like our ADCO...
It fits very snug.
The zippers are quality and work smoothly.
It comes with little weights used to toss the straps under the rig.
The color matches our house so it technically camouflaged
One last push for covers is for uv protection. The sun here in Colorado is murder on paint and fabrics. I noticed a definite shade difference from uv fading on north vs south facing sides on the cover just in the year we have used it. That fading is on a $300 cover rather than on our paint job and fiberglass cap.
