Whereever overnighting at Walmart is allowed, I always find a side slot that will allow me to open one slide over the curb--this gives me room to put the opposite slide out without protruding into a driving lane. Just have to use some logic to see where most of traffic is, and stay away from that area. Generally, it will be obvious where the best area is to park, especially if there is already a unit exactly where you would like to be. :
