I have not tried to renew my registration since the reported issues. my title came from a transferrable NH reg from the previous owner.
Completely hit or miss, leaning more towards the miss. Give it a try, register historic, never mention mini truck. just renewed my registration a month ago.
I'm trying to inquire with the DMV through a friend who works there if an early 1990's ToyotaTownAce Truck will make it through. Hoping since it's a Toyota will be good
