I don't mean for show
As delivered my trailer floor is just plywood with some cheap grey paint on it. I figure hot rubber + rocks will chew through the paint, then I'll start getting water into the plywood and it will rot and tear up eventually.
Re: front straps - I've been test-fitting a solution using axle-straps through the wheel itself down low, seems to work without having to raise the car in the trailer. I'll snap a pic in a few minutes when I'm out there.
