Thanks for the info. When I check the New York state DOT website the only restrictions I could find for the Niagara Scenic Parkway was no commercial vehicles. Now New York City Parkways and the surrounding area has restrictions for RV and commercial vehicles listed.
I have read on other forums that RV's can and RV's can't be on the Niagara Scenic Parkway. So I guess to be on the safe side I will probably just stick to our original plan and take NY 104 over to NY 18.
