I was more than happy to go with the lower GVW when I registered my truck, the differenace in tonnage fee between 12K & 24K was painful!
Woulda registred it as a collector vehicle, but then the only thing I can legally haul with it is whomever can fit in the bench seat. Not much point in a truck you cant haul nothin with!

1956 GMC 370 dump " 'Tater "
1970 VW Volksrod "the Black Bomber"
2007 Chevy Avalanche
2020 Jeep Cherokee Trailhawk,
2005 Harley Davidson FLHTCUI

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
