Thought I'd share this here too which I wrote at that 6x6 G63 AMG FP post.
I am sorry Travis but I had to, those local tribes can still do so much much more better off even with a MUTT. Out millions of advantages, I type one. Independent suspension!
I still remember our MUTT lost one its rear-axle while climbing steep. We were already at 4,000ft. when that happened. We abandoned the vehicle and went up. Later in the night, due to windchill at the top, we decided to switch camp and come down at a lower base. So we stopped by, and the MUTT was owned by a US Marine, so consequently he insisted that one of us support him and he'll mend it there. So I, being the passenger came forward. Now to note that is I am totally crap at mechanicals but the owner guided me and we pulled the front axles, repaired the bearing and inner rings with a small torch, some grease and handy tools from the MUTT, put those front axles at the back and one working from the rear to the front, threw the faulty one in the truck and exclaimed, mentlegen, this may now be 3x4 but push is better then pull and off we went. All this process took about 1-1/2 hour.
This first picture is while four of us were pushing the car to put something in place with precision as the handbrake was taken out, few of the guys thought about doing some light-painting.
This second one, is taken after climbing a while after when we abandoned it.
Here's another without the zoom:
Just after we got to know that we're, well fucked. It won't climb because the lack of push.
