well I have posted this about 1 billion times. windows and doors should have radius corners. people who build campers/trailers with square corners either don't know what they are doing or are to cheap to care. 90° corners will stress fracture at the corner. all airplanes, boats, and RV's use radius corners on the windows and doors these days. that glass probably isn't even safety glass. what's going to happen in an accident? do you want to be next to that thing with flying glass shards? sorry to be a downer but I just have to speak up when I see crap like this. highdesertranger
