From your New York DMV:
"A driver with a Class D license can now operate a personal use vehicle (for example a rental vehicle or a recreational vehicle or RV) with a gross vehicle weight rating (GVWR) of 26,000 lbs. or less that tows another vehicle that has a GVWR of 10,000 lbs. or more, but the gross combined weight rating (GCWR) of the two vehicles together must be 26,000 lbs. or less.
Note: The requirement for an "R" endorsement (Class D or Class E license) to operate a recreational vehicle with a GVWR of 26,001 lbs. or more remains in effect."
From another site, the "R" endorsement is apparently a driving test to show proficiency but I can't seem to find that information on the NY DMV site.
