in my state touching the vehicle with a loaded long gun is illegal
Huh?
If you are licensed to carry a handgun you may carry it loaded in or ‘on’ a car. Not so with long guns here in the People’s Republic of NY. A fellow a few years back pulled off the road into an old quarry a few days before big game season opened. A state trooper on the highway saw the guy with a target set into the cliff, shooting off the roof of his vehicle. He was summarily arrested for having a loaded long gun in contact with a vehicle. The NRA went to bat for him but I never did find out the outcome.
Suffice it to say you can’t have a loaded rifle/shotgun in, or even on a car.
