I did these on my first Rubicon and I did them because I NEEDED to. This time I did this install before I my corners were bent like pretzels.
I picked up some 3x3 angle iron from a buddy of mine and built a cross member support for my LJ. When I add the 32 gal tank I will need to cut out the inner cross member. I like to add/brace the bumper cross member to provide additional strength and crash protection for the rear of the Jeep and the new 32 gal tank.
Its an easy job and I have done it before and have a write up below. These pics are of my current install.
