Plymouth MA- trip help
Wing trike, Cousin Ed has the right idea, but he doesn't realize where Kinston is.
From your location forget I-77. Get on I-95 near Wilson to either I-64 at Richmond or US17 just above Fredericksburg. Cut over to I-81 on one of these routes (the US17/US29/US50 route will be all very good road and many miles shorter) then I-81 to I-84 at Scranton, to I-90 (Mass Pike), I-495 south, and then US44 east into Plymouth. This will bring you around DC, Philly, NYC.
An alternative for you, being in Kinston, would be to go up through Norfolk, then the CB Bridge Tunnel and US13 up to Wilmington. But that would mean the NJ Tpke, which isn't really as bad as most people think, as long as you cut off well before NYC.
The first route is probably what you want.
When able, I'll check on places we've stopped in eastern PA, which will likely be your 400 mile halfway point. I do know there's a very nice Boston/Cape Cod KOA on Rt 44 in Middleborough, MA, only 15 miles of excellent road from Plymouth. We stayed there for 2 months last year when our granddaughter was born.
