I built the skid plate for my Massey Ferguson 1529 using 1/4" thick 6061 aluminum. Yes, I know it sounds too thin and it isn't steel. It took the 4x4 folks a number of years before they finally realized they didn't need to drag steel skid plates on and over the rock washes in the desert Southwest. I ran aluminum skid plates on my engine, tranny, and gas tank for years and it handled everything I could throw at it. The competition vehicles we used were equipped the same way and the only difference was that we beat the snot out of them compared to a non-comp vehicle, and we never had a skid plate induced failure.
Here is my 4K pound Jeep sitting on the 1/4" 6061 aluminum gas tank skid.....and that was the easy part of the rock wash. And for what it is worth, I also ran an aluminum steering (tie rod & drag link) and aluminum suspension (except for the the steel coil spring).
