Merrimack N.H. at the outlet mall I delivered to this morning. Might move to Mr Crappie's truckstop in Bow that hawk recomended 26 miles away.
Not a heck of a lot of choices up that way. You have the TA in Greenland, the Pilot in Sturbridge, Mr Mike's, and there's Flynn's in Shrewbury. Also, you could head down to Springfield, which would put you smack dab in the middle of NE. But Mr Mike's is my place if you have to idle, or want some peace and quiet (I know... contradiction).
Londonderry, NH also has a small truckstop on 93-exit 5. It's small, weren't a lot of trucks there, and has a deli. Lots of good sammiches and salads and stuff.
