damn Sonny didnt mean to hit a nerve with the 7.3L..wow you have had nothing but issues with it..sounds like maybe a Cummins 6BT with a stick would be a good swop in?
anyway Ive been using Maine tags on all my trailers,never had an issue yet..a 12yr tag goes for $225. Maryland wants $125 for a flatbed 12K trailer tag..PER YEAR..
so that was a no-brainer to go with a Maine tag....https://mainetags.com/
