Blew out back RH window with my camper tonight,,,, Confused

Not sure if this was mentioned or not (I didn't read all posts) but I always try to avoid the tight turns you described while on pavement. On the road or in parking lots (where my manual slider is usually in forward position) I try to make sweeping turns.The main reason I say this is not just the chance of hitting but the extreme forces it can put on the tires and undercarriage of the trailer while it is dragging around sideways.
