29RE CC Silverback slide

Our 2014 (29RE CC) slide on driver's side with stove/fridge/two lazy boy chairs when "in" is about 3 - 4" up off the main floor along the edge...The other side is nearly flush with the floor. If you are getting something from fridge and stand on it it goes down slightly. On the outside all 4 sides are tight to the walls of the 5er..

Any one have this situation with any slide when in?
