I looked up your trip on GoogleMaps and it quotes 545 miles from Norfolk (USNavy) to Gloversville...
That's along the coast and riding much too close to NYC for comfort.
There's another route, Rt95 to DC, Beltway and Rt270 to Frederick MD, Rt15 to Harrisburg PA, Rt81 up to NY State and Rt88 around the Catskills...
This route totals 620 miles or 6 tankfuls
Should make a pleasant 2 day ride.
If you cruise at a steady 60mph (boring, I know!) you should be home without any trouble.
Of course, you can pack only so much (bags) on a Savage...
