Oh yeah.... using mine in the mountains during subfreezing weather caused condensation to build between the insulation board and fiberglass body thereby releasing the glue that holds the insulation board to the fiberglass roof. The escape hatch is helping to hold that piece up, but you can push on it and it wants to restick but won't.
Even though I vented the camper each day while at work and above freezing daytime temps the condensation built up so much the jacks circuit board went bad from moisture. It was soo cool to find a new circuit board for fifty bucks that was the old style corded remote. Never want the cordless.
