I have a professionally custom made bracket that cradles and reinforces the cargo box on the floor of the Ram 2500. This mount supports the weight of the twin compressor. weighs about 3-4 lbs and ties into the floor from beneath the truck. I had it in my 2018 powerwagon but I cant see there being much difference in other 2500 models. A must have if you run a twin air. This is a custom made unit. $75.
