I worked with 6061 T6 years ago. I believe that it's perfect for the job. As you said, clevis mounts and winch mounts will have to be backed with steel reinforcing plates where they are bolted through the aluminum.
I was thinking that 1/4" Al plate would be the minimum thickness that I would use.
Does anybody know the thickness of the steel that is commonly used on commercial Jeep bumpers?
I need to do a weight comparison of same sized plates of 1/4" aluminum vs say 3/16" or 1/8" steel.

If I'm not mistaken, ARB makes, or has made, aluminum bumpers for other vehicles, including the Isuzu Trooper. Let the aftermarket know what you would be interested in and I'm sure someone will step in to fill the void. I for one would be very interested in a selection of aluminum offerings.

I would think If you want the best bang for your buck I would go with
A514 AKA T1. That would be 100,000 psi steel. Most C- channels are A36
36,000 psi steel. The 6061 T6 would be 35,000 psi
The steel bumper would be thinner, easy to weld and cheeper only a small percent heavier.

I believe that you would still have to use the winch plate, however if you use a configurated T for the clevis mount and make the mount out of 1/2" plate aluminum T6061, you would have a strong enough configuration. The link below is to a fire apparatus manufacture that makes its ladders out of aluminum. http://www.e-one.com/index.asp?n=70&p=70&s=70&pid=9

They should be down the street from you. Most other Fire apparatus mfg make their ladders out of Both steel and AL. If you see a ladder truck with a painted ladder it is steel, unpainted it is AL reason being is so you can spot fatigue, cracks, etc. I would much rather climb a 100 foot steel ladder than a 100 foot AL. At around 85 feet the ladder starts to wobble and that is with no water flowing and on a calm day.
Aluminum versus steel aerials is a personal preference and I am biased...

They have got to be laying around all over the place.
