I had a similar thing happen on day one with my present TT. The bunkhouse door swings in to the bunk house... It cannot be seen from where the slide control switches are. I did not close the door. The damage was minor, and at that time the door was not really needed for our use, so I simply removed it. A few years later and things changed, and I really wanted a door.
So I came up with a solution. I installed a magnetic switch in the door jamb/hinge side of the door. Almost impossible to see even when looking for it. Ran the low amperage wires over to where the switches were, and installed a 30 amp relay. Now the slide will not activate when the door is open.
The actual install was pretty easy. The planning took a little brain power.
With some thought, I bet this fix can be adapted to just about any door in any RV. I know I will do this in my future ones,
The cost was less than 5.00 ordering the parts from China off of Ebay.
