We have a pickup truck and a 21ft trailer. When we first started traveling in 2007 we ended up on the parkway and pulled over by police. I am under the impression that they only want cars and they also restrict propane. In March we were trying to get to a campground in Copake NY and we could not seem to find a way to get to it other than the parkway. We drove around and around for 2 hours. The Garmin kept sending us onto the parkway. We had stayed at the campground n the past and knew that we could get to it somehow. We did eventually figure it out... don't remember what we did but boy was that frustrating and such a waste of time and gas:( It is my understanding that in NY only cars are allowed on any road called a parkway. I don't know about class B's though.
