We have been full time for ten plus years over time my wife and I noticed the kitchen floor is bowing long ways with the slide out. The bowing floor is under the linoleum. If you're in the RV and standing in front of the kitchen countertop the bow extends under the water heater into the living room and gradually decreases towards the right side a couple of feet in front of the kitchen pantry. The rising floor is deforming the paneling that the propane detector is mounted on. Is this frame flex?
