The kitchen slide IS different as it is on th multiple motor schwintek system. In videos it shows that it stops auto when it hits an obstacle or the end of the run when the trim hits the wall or closed when the slide hits the outer shell. I will check the outside trim tomorrow when I see the trailer again in storage.
Today I bought ball valves for the low point drains, a three way valve and hose to attach before the pump to change to suck in anti freeze instead of on board fresh water. Hope to install Sunday.
