Slide not settling into position

Once you push it, does it stay OUT? Or does it fall back inward? If you do NOT push it out, does it leak? I have had a few RV's that this type problem comes up when you have the floor Rack system. Yes, it is the weight of the room problem. Usually when a slide room extends, it passes the center pivot of weight and the upper swings outward a few inches and seals. The rack system then pushes the bottom out tight. Have you tried to STOP extending the room when the top hits the top Or does it never hit the top? The ones I have seen the top hits first and when the bottom is pushed at the seal, the top of the room swings in an inch or two. YES, you need to contac Newmar and see what they say. It would be best if you could use a smart phone to take a few pics or even a short Video showing how it is in and you then push it out. Pics help a lot at the Factory. Doug
