We have stayed in Flying J's & Walmart's - if we pull in and don't feel safe - we hit the road and try the next area. There was only one time we left a Walmart - when we arrived the rv parking was quite full and one of the only spots was near the delivery docks, there were about a dozen delivery trucks lined up making deliveries - we passed thinking the noise would keep us awake the few hours we planned on being there - drive down the road 20 minutes and found a Walmart that closed at Midnight and was very quite.....no problem there!
By the way - I call ahead if staying at any Walmart, Cracker Barrel, Flying J, K-Mart and ask if overnighting is allowed and where do they prefer we park.....and of course when we stop we usually go in for a bite to eat or snacks and let the manager know we would be overnighting and where we were parked.....just being courteous!
