I cut mine off, no regrets. I slipped a thin piece of sheet metal with the edges taped behind them, and with a new razor blade cut them off. The metal backer was about 10" longer than the window to prevent any "extra" unwanted cutting on the vinyl walls. Way easier to fold the top up, and you can open and see out the windows without having to go outside with a ladder. The velcro strips pealed off the vinyl easily after being in the sun, a few were already pealing off on their own. There is a reason new campers do not have them.
