When I picked up my new ship arriving in Houston from Germany, I did a
careful inspection of the tailer for damage. And sure enough, one of
the external feet had been tweaked - probably due to a steep ramp
causing the bottom to scrape and catch on something.

So document the trailer's condition carefully when you drop it off, and
have the buyer do likewise.

These ships aren't built to handle our relatively long and low
trailers, so handling damage can easily happen.
