Parking at Wal-marts

I park at wal-marts and shopping centers alot, usually i try to find big malls with walmarts and lowes etc and I pull in the back and take my break there...

East coast parking is slim to none and I'm not going to pay to park in some of these truck stops, ill find either a large shopping mall or an on ramp.

 

My father is an actual Wal-Mart Private Fleet driver and even he cannot park at ALL walmarts. He ha a list of stores with no truck parking

I usually take a look at google maps before heading somewhere and see what's around and then I look at the satellite view and see if I can find a strip mall or something to park behind.
