I have a power sliding door. The cables that unlock the door broke, and the door will not open from the outside. "Gotta get rid of that electric door" I thought to myself.
I am currently considering ordering another van (longer with more options) and I went to the dealer to look at a *cargo* van with no side window and a manual slider. That door took so much effort and speed to close, and was so loud in order to get it closed properly (while closing from the inside), that I would not even think about opening and closing the door in a campground.
I think part of the problem is no insulation and no window to add weight (thus momentum). The window also keeps the door from ringing like a drum when you do pull hard enough to get the door to close and latch properly.
