Kevin put some kind of gutter over the door on our Uhaul
. Our FirstUp fits and sits into that groove when we prop it against the door. Granted it does not stop all water, but it keeps a lot out, because it keeps it tighter. We have wind curtains that we use for lighter rain and even too much sun, in addition to the bug screens. When it is raining hard, Kevin covers the whole screenhouse with tarps. We had a storm at Blue Licks, KY last summer that knocked out the campground water due to a fallen tree, but our screenhouse was nice and dry. We like camping with it, as it gives us so much more room. We just got back from a week and a half when we did not put it up. We survived, but we are happier when we don't have to assign the end of the camper that one of us can be at and have the advantage of the additional space.
