I do know that Maryland bumper height max is 28 inches from the ground to the bottom of the bumper.
To get the most accurate information, I would suggest that you call any local NH Inspection Station or call your local NH State Police barracks and I'm sure they will be more than happy to give you the information. Or you could always go to your local library and look in the NH Traffic Law book. HTH
