4x4 Iron rear bumper , NWP 43 gallon bas tank, who\'s bought one? I am getting ready to order a 4x4 Iron rear bumper with swing away tire carrier and maybe side armor. Questions for those of you who have one. I am also planning on installing a NWP 43 gallon steel gas tank. Can I keep my Class 3 hitch with the new gas tank? If I can't then I should get the receiver built into the bumper. Also, I am thinking of having 4x4 Iron make mine with a double swing away. One side would be the tire, the other I would mount a double gas can tray and fasten my Hi-Lift on as well. Anybody do anything like this? Back when I had my Bronco, I saw several similar designs on other rigs. Too much weight on the bumper? Suggestions? Comments? Pictures?
