Where would you put the rdr, rdl, fdr, and fdl?
As DumbTruckDriver said, there's not really a good way to load them.
When I have to load one, there usually aren't any floor stops, just the shelves. On the rare occasion that there has been RDL and/or RDR, I put those right where they'd go in a standard package car; right inside the back door on the proper side.
Besides that, I load 1,3,5,7 up the right side and 2,4,6,8 up the left side, leaving an aisle in the middle. I aim to make the whole load about the same height by the end of the preload. Don't stack the 3000s 5' high when every other section is only 2 feet high. In that case, I'd tighten up the 1000s and 5000s a bit, and spread the 3000s out a little. My goal is for at least the first part of the day, the load shouldn't be rearranging itself whenever the driver hits the brakes.
