Hey Kelly, the mounting hardware for the Truxedo Deuce tonneau cover part # TX772801 that you referenced is a little less than 3 inches wide when measured from the inside of the bed rail towards the center of the truck bed. So it looks like you have right at 3 inches of clearance between the tool box and your bed rail so this would work great.
