Starting the process to purchase a new TT...sold our Crossroads Slingshot...now want one with a slide out. We use a storage place close by and cheap...but no covered bays. Thinking about a TT cover....
I leave my vents just cracked open and have 2 Dryz-Air things while it's covered. Never any moisture issues. The breathable cover drys very quick when the rain stops.. We get a lot of rain where I live, but not so much humidity..
I have to drain/refill the Dryz-Air things about once a month.
