Probably not a problem, but should be looked into.
After you have closed and latched the rear shell, peek over the slider and into the TM. Make sure that nothing is higher than the tops of the lower walls - such as the back of the chair, or something stacked up on the couch. Also, make sure that the chair, which is now backed onto the slider, is at least 6 inches away from the door-side wall. Just to the right of the door as you step in, and down on the floor, is a wooden triangle that connects the floor to the wall. This triangle can't move, and if the chair is up against the sidewall, it will push against the triangle as the closing sequence progresses.
Keep us posted ...
