Usually about two or maybe three times a year, my load, including truck can weigh in over 18,000#.
So I run 24,000# plates. It gives me piece of mind.
The thing I don't like is, Missouri does not issue a rear plate for anything over 12,000#.
When traveling out of state, I've had a few LEO's eyeball me until they see the front Missouri plate.
In place of the rear plate, there is a Stovebolt plate.

Oh, the tow vehicle is a Ford, eeeek

Of all the things I've lost in my life, I miss my mind the most!
