Sheds shifting in the trailer is a lot less of a worry around here than 60 mile an hour wind gusts are. Not sure I buy you're logic that sleds shifting is going to put a truck in the ditch unless you are pulling too big of a trailer with too small of a truck
I have similar stuff in my trailer. Works great for quads, sleds have torn it up, but for the price of lining I could paint it once a year for ten years to keep it looking good
