Our ADCO Custom cover with Sunbrella fabric is almost five years old. I cleaned the mold off with 1.5 cups of bleach and 1/4 cup of dish detergent per gallon of water a week ago but the process may have damaged the fabric. It feels dry and thin relative to how it usually felt. Started looking for a replacement in the event we need one. Got a $1,472 + S&H quote from CalMark for their new Weathermax RV fabric; they say that they can’t get Sunbrella fabric right now due to supply chain problems. Looks like a new ADCO Custom cover with Sunbrella fabric will be ~ $660 less than a Calmark cover. Has anyone had both? Really good mold resistance might be worth the added cost of a Calmark cover for us. In our experience, Sunbrella will get moldy but it will also outlast the thread material. My only complaints with our ADCO Custom cover is the zipper thread let go around year three but that was repaired under warranty and the velcro at the bottom of the entry way flap will not last more than 3-4 years.
