2015 Expedition 38K bed slide

Bought a new 2015 Fleetwood Expedioin 38K. This floor plan has a bed that slides down within the bedroom slide. In other words you put out the bedroom slide and then the mattress itself is sort of folded in half and has a power slide to bring it flat. The advantage is that it gives you a full length closet.

We have had nothing but trouble with the mechanism working. If it does not work you are sleeping on the floor. Wife not happy. The problem is the worst of all problems -intermittent. Had the Fleetwood service team look at it this week at a rally and they had never seen the sliding mattress before. They did the best that they could. It started to work and none of us knew what we might have done.

I am sure I am not the first one that has had this happen. Anyone else familiar with the issue or a fix?
