There does not appear to be a listing or general discussion of food trucks closer to 128 than to Boston. It's probably a short list. Offhand I can't think of much other than Fred's Franks in Wakefield and the itinerant strawberry truck that stationed itself in rotating Woburn locations when I worked there until 2007. I don't know if he's still around. I recently noticed Tijuana Trolley in North Billerica but know nothing about it, and have heard good things about Marko's Mediterranean Grill in Lowell.
