I reg. a past truck @ my GCVWR thinking I was doing the right thing, turned out all I was doing was giving my hard earned $$$ to NY DMV for free. Register your truck @ what reg. says it weighs. You can also reg. your 250-2500, 350-3500's as a passenger vehicle because you put a T.C. in it, insurance, reg.,tolls.... are all alot cheaper. Tolls alone will fill your tank 4-5 times a year. Inquire @ N.Y. DMV for the proper form. They'll tell you, you can't do it because of the weight, have a pic. of truck w/ T.C. loaded when you go there. DO NOT take "no you can't do it" for an answer it is 100% legal. No offense to anyone out there but DMV does not have all the brightest stars.
