Hopefully someone comes along with something that fits perfectly.
If not, I'm wondering what would be involved with taking the E series model and modifying it to fit? Or at least measuring one and see if it is feasible? If it was just a matter of splicing in some more material in the center of the windshield... If it is both height and width issues prob more trouble than worth. Maybe someone at campground would let you try it on for size.
The Adco covers are very useful wouldn't be without it. But they do have a life expectency..mine last about 2 years.
