Just installed this CM Flatbed "Tradesman Deluxe" (TM Deluxe) on a 2018 Duramax 3500 truck! This is a sharp truck and we think this bed looks especially nice on it with the steel tread plate decking. Not to mention the usability and versatility with so much locking storage - keep your tools and gear safe from the elements with a CM Flatbed or Service Body from Midwest Motors in Eureka!
