Hold down plates are at the front and rear of the shell.
Their purpose is to hold the frame to the shell.
The front plate is obvious on the older trailers, with 3 horizontal rows of rivets.
We increase that to 5 rows.
The rear plate is smaller, since the rear access door is in the way. But again, the more rivets, the better the hold down.
Also at the rear, installing a bracket on the outside of the frame, underneath the banana wraps, adds considerably to the holding strength. Bolts go thru a steel plate placed in the floor channel, the floor channel, the floor, and then thru the new plate.
Using "fender" washers in that area helps too.
