I spoke with my contact at Lippert about the Underchassis Double Bin Storage Unit, part # LC236558. They told me that the mounting angle brackets are 1 inch wide.

They gave me the distance from the end of the storage bin to the edge of the mounting angle. I have a photo of the storage bin with the dimensions noted. The distance between the mounting holes is 70-1/2 inches, and the edge of the first mounting bracket is 14-3/4 inches from the outside edge of the bin.

Ideally that center bracket also gets attached to a crossmember under the chassis. I reached out to my contact at Lippert and he said NOT using the center bracket won't necessarily reduce the weight capacity, but over time you might notice the storage system droop a bit in the center. If you can't utilize the center brace, I might just try to keep the heavier storage items towards the outside ends of each bin.
