The door would no longer open. There were four people inside the motorhome, and none of us could open the main entry door. We were effectively trapped inside the RV through the primary entrance. Because we could not open the door, I climbed out through the passenger-side window so that I could get outside and retrieve tools. While climbing out of the window, I fell and injured my leg and back. After getting up, I went to the motorhome’s tool compartment and retrieved a screwdriver. I then passed the screwdriver through the window to my friend, who was still inside the motorhome. Since the main door could not be opened using the broken handle, my friend had to remove the screws securing the inside door latch/handle assembly. When those screws were removed, the assembly came apart and the internal components became loose. This disassembly was necessary so that we could gain access to the internal latch mechanism. My friend was then able to manually pull one of the internal latch components, which finally released the door and allowed us to open it. The latch assembly and its components were subsequently removed from the door. We have saved
