Topper and Vent Options Offered By Dealer for New Purchase

"...Our Avion Platinum came with slide toppers. In wet weather where we camped a lot you had to get up on the roof any way to sweep the needles and leaves off before retracting. No different than if you did not have them..."

I bought the slide toppers to reduce my chances of falling off a ladder or the roof, and to save me work. There's no way I am going to sweep them off before bringing them in. I doubt many people do.
