About 6 months ago on a rainy day, I went inside the coach to pick up something. On the way out, my left foot slipped of the wet threshold, my right leg bent behind me and I flew out on the grass.
It was one ugly fall. My right knee still hurts at night.
Today finally I got around to do something about it (it was raining again
. Installed two non slip strips made by Safety Step. There is no rubber gasket at the bottom edge
of the door, just brush like seal. So there is no damage to the seal.
I would recommend if your door has the same threshold, to do something about it.
