Rob, when you roll your back drop, do you have it set up to come completely off or to fully roll to the hard top or radar arch?? If you leave it rolled up to the hard top, do you find its a struggle with the extra thickness of the towel to get the strap to fit?
On mine, I have sections that are able to fully roll up to the arch.
This is why I love my center console. No canvas to worry about. Just one little piece over my electronics, and one over the rear seat. Less then 20 seconds and both are off and on...
