RV Sunscreen | Our Photo Gallery
As far as the Magne shades, they are an excellent quality product and Roger is a pleasure to deal with. We initially wanted the Magne shades but found that because the front cabinets in our Bounder extend down in front of the windshield, the cabinets would have had to be unfastened to get the magnets installed. We were unwilling to do that, so we passed on the Magne shades and went with a different type that snap on.
A forum search will find dozens of previous threads about the various types of windshield sunscreens. Good luck.
