Yes, I have had 2 trucks that were registered with GCWR. I did it because of using Maine tags on a few trailers. In Maryland when using Maine tags on a trailer DOT will put all the weight of the trailer on the truck which will result in an overweight ticket if you don't have sufficient GCWR registration. Maryland DOT targets trucks with Maryland tags pulling trailers with out of state trailer tags. If you have Maryland tags on truck & trailer the weights of truck & trailer are separated by DOT and are not targeted. My 250 was registered for 23,000 GCWR and cost $384 every 12 months for tags.
Due to purchasing a new heaver 5th wheel, I took the Maine tags off the dump trailer paid for Maryland inspection and put Maryland tags on. Changed the now 350 DRW to 14,000 GVWR tags. I went from $384 every 12 months for tags for the truck with a 23,000 GCWR to $140 every 2 years for the 14,000 GVWR.
To up the GCWR of the 350 DRW to accommodate the 16,000 5th wheel, truck tags would have cost just shy of $500 per year. When you get into a trailer over 12,000 in Maryland, Maine tags just don’t make sense and the target for being pulled over by DOT is removed. I still have 2 small trailer with Maine tags but will not exceed the GVWR of the 350 DRW if DOT puts the weight of the trailer on the truck. The advantage of Maine tags, no state inspection of trailer, no state tax on trailer and tags are much cheaper for the trailer.
