Overnight location - 1/2 way to FL from MA

TRIP Update; Just got home from a GREAT trip. Thanks to all who replied to my original request. Took 301 both ways and it was well worth it to get around DC area. Purchased the "RVovernight" app to find places to stay. Expensive for an APP but it made me feel a lot better about finding places. Stayed at Walmart on the way down in NC and one Crackerbarrel on the way home. Both quiet and well lit/safe. Thanks to the app. Best news of all - we rushed to get back to MA before the ice storm and made it but it was very heavy rain for 14 hours of driving. NO Water LEAKs. checked real good when we got home.
Had to change one coil pack and spark plug in cyn. #6 because of rough idle and engine stumble (2003 ford v10). Thanks again to all ...
