I think I've seen pics of your Ram in magazine articles haven't I? So do you use Rockwells for the tandem axles or something else?
Yes the Dodge ram got very popular and made it into 15 magazines worldwide, we were sponsored by Dodge and we competed with it and beat the living hell out of it for 11 years. 140K miles on it and still going, been on its side, under water 7 times, just keeps going. It is all stock except for the exocage, suspension and axles, which you guessed right are Rockwells.
The Jeep we used Dana 60's in the rear with a twin output T-Case ( Dodge 205) and a high pinion 44 in the front.
For some fun google, Dodge T-Rex on youtube and you should see about 30 videos of the T-Rex being abused.
