Once I get setup I can build you one out the same materials of my proto. They are poly coated so it helps with waterproofing and water shedding.I'd love to have one of these on my F150. If there was a production model I'd be all over it.
I think brushing snow off is a small price to pay for having a nice, insulated area to hang out while it is set up. I have a buddy who has a slide out camper that has the same problem, he now knows that he has to brush off the top before pulling it in.
