Not sure of your exact route or how much time you'll have, but places I'd recommend and things to do.
Central NY:
Turning Stone Campground Exit 33, Verona, off the NYS T-way. Very nice F/H site w/ paved roads/sites. Casino nearby w/ very nice BBQ rest and Buffett joint. Boxing Hall of Fame nearby. Pepis Pizza (top notch)
West Canada Creek Campground, Poland NY (approx 12 miles NE of Utica (exit 31 off the T-way). Awesome owners. Fish, tube, canoe or kayak on river. Old Forge nearby. FX Matt Brewery in Utica. Piggy Pats BBQ (1/2 hour away)
Adirondacks:
Old Forge Camping Resort, Old Forge NY. Sites area tad close, but all shaded. Cannot run A/C or water heater on electric---so can be a problem if very hot/humid. Hiking, kayaking, canoeing, water park, Old Forge Hardware store. Check on size as we had a 35' 5er and no problem.
Northern NY:
Swan Bay Resort, Alex Bay NY. Right on the St Lawrence Seaway. Brand new. F/H (no cable tho). Tour boats, fishing, sightseeing--Bolt Castle & Singer Castle.. TI (thousand islands) bridge to CA--worth driving or walking across.
Eastern NY/Lake George:
Many campgrounds:
Main one is LG RV Camping Resort on Rte 149, 1/2 to a mile or so from Rte 9. Sites are very close. F/H. Lot of shaded sites and fair number of open sites. Lots of CG activities and acts in CG's own "theatre". Lots of kids. Traffic is a nightmare Fri afternoon thru Sun Afternoon from I-87 to CG (plan on 5-10 minutes extra or bit more)
Ledgeview RV Park, also on Rte 149 lil ways past LGRVR, very shaded, lots of seasonals, less kids, sites fairly close.
Moose Hill Lock RV Resort, also on Rte 149 few miles from Rte 9, IMO the best one. H-U-G-E sites, all F/H. HUGE heated pool. All sites separated from others w/ tress. Stone/gravel roads, stone/level sites. LARGE granite rocks are fire pits.
What's nearby: Great Escape, Lake George, tour boat on LG itself. Ft William Henry. Veterans Mem Drive, Saratoga racetrack, tubing, Lake Placid (approx a couple hr drive 1 way), Ft Ticonderoga, Ausable Chasim (they have a CG too, but don't know anything about it), Barnsider BBQ & Pizza Jerks in LG, Vermont Teddy Bear/Shelborne Muesum, Ben & Jerry's/Von Trapp lodge all in VT and a decent day trip+. Local fairs may be up and running.
