A bunch of sheet goods, salvaged plywood or something similar, stacked high, bouncing around on a trailer, flapping in the wind.
The very first thing I look for when rolling up behind a trailer is how their crap is tied down, or not.
Too many folks on the road think that because it was so freaking heavy to put on the trailer, there's no way it's going to come off. Nah, we don't need to tie it down, it'll be ok.
Dude had it tied down with something I couldn't quite make out so I skated on past.
I've seen boats laid up sideways on trailers from one good bounce. I've seen furniture hop right out of the bed of a pickup.
I've seen an entire
I've run over a small sailboat that was not tied down to the trailer...what was left of it after it hit the freeway in front of me.

Ya know, it you don't want your boat anymore, set it on fire or something. I don't want to participate in your insurance claim.
