For what it's worth, this question & responseis from Frequently Asked Questions under Buyer's Tools on Crossroads' home page:
Q: "Should I cover my RV with a tarpaulin or canvas cover when it is not in use?"
A: " It is not recommended that your RV be wrapped with any type of cover. The rubber roof material
needs to breathe and be allowed to dry thoroughly to prevent mold and mildew. According to the
roof material supplier the chalky look of the rubber is normal. Parking under an overhang or in a
large garage is acceptable."
Wish I had access to a large garage. After 7 seasons outsidemy graphics are deteriorating rapidly. Dealer in Denver is putting together the costs to replace. Waiting for Crossroads to respond back to them with part numbers and costs. Then again, the Denver RV Show is in 2 months. New rig? New truck? Hmmmmm.
