There is an access road from NY Rte 46 into Lock 21, so an RV could meet you there. There is some parking in and around the lock, butI do NOT know whether it's open for RV's.
I rode in today, and the picnic area on the north side is fenced off - looks like there might be some construction work happening soon.
