Front window cover
I don't know why Hi-Lo decided to go with the exposed window. I have one of my bubble levels break about once a year, from rock strikes, and am happy that my '89 has a window cover. A friend of mine, with an Airstream, had to wait about a year for them to ship him a replacement front window for his trailer. He travels off the pavement, like I do, looking for trout.
There's got to be way to fit a bra on these later model trailers, like those used on the front of cars, to take the rock strikes.
