Propane is not a problem as long as you turn the tanks off before you get to the tunnels and some of the bridges. We traveled up the entire east coast and went through every tunnel imaginable and they just stopped you to ask if the tanks are turned off. None of them even checked. Some people claim that you can't have propane with you but I found out differently.
Be forewarned if you elect to follow BarabooBob's advice. You may find a toll booth attendant that know and follows the rules who will deny you access to the tunnel. Then you will have the option of exiting to the surface streets or turning back the way you came. Just because one toll booth attendant let one guy through, doesn't mean they all will.
