No way are you going to fit a 40" Swamper and a Cooler/Jerry cans on the back of a 40.. They are only about 60" wide, 55" at the back where the radius starts, so you man need to ditch the cooler/jerry cans to make it work.
Most guys running above a 37" are ditching their spare tires and carrying plug kits, or putting the tire in the truck on the floor of the tub.. Thats just too much weight hanging out the back of your truck..
Jim AKA Solid Rock Off road, is now our Official Bumper Expert!He is Very Busy Filling orders, but once things quiet down a bit im sure we will be working on a 40 setup.. id think 37's would be max!
fyi a 40 can be mounted with a cooler/jerry can set up....see pic
