I was thinking at the begining of this thread, that this must be a joke.
If these numbers are true, I believe that dot, your taged classification tax like FET, and cdl requirements will change the rating in the end, probably because of liability.
Ever notice how many trucks and flatbed trailers and such are tag rated under 26k, even though they can handle more? Over 26k that you have a federal excise tax and cdl is required.
I wonder what a class 4 or 5 would tow, heck you wouldn't even need a class 8 truck till 200k
