When I arrived at Ft Bragg in 1990 the ambulance unit I was in had JUST gotten the brand spanking new HWMMV ambulances. Two platoons of the boxy 4 litter models and one platoon of the sleek 2 litter ones. I discovered that the diesel sounds funny if you wind them up to 70+ mph (speedo only goes to 60). Kind of a Daaadadada sound.
The 4 litter ones could only just pull 60 mph with their extra weight and aero penalty. They weighed right around 10,000 lbs empty and were SLOW with that naturally aspirated diesel.
During the 'storm we got some really mixed fuel. Some swill JP1 that probably cut the ho by 50% and some hot JP5 that made them feel like hot rods by comparison.
One day I was cruising along the hardball in the desert at an indicated 50mph when an M1 Abrams cruised by in the sand beside us doing at least 65. In a 70 ton tank!
The drivers seat had springs in it but the passenger side was just a pad on the box that housed the two massive batteries (which got hot in the summer).

M1 doing 65, wow! Must have been a sight
I have no experience in a H1. Looking forward to getting acquainted

When I was stationed at Ft Polk my room mate was a medic. We would go to the field for 2 weeks at a time and in the summer it was not fun at all. From time to time I would ask my buddy if I could hang out in the back to the ambulance with the air on, it was heaven.
I was on an office call and delivery driver passed me! Looked imposing
Driver just dropped her off at home. It's his 3rd H1 this year.
said got lots of attention on the road.
of course I had to immediately take it for 20 mile drive and get some fuel
what a beast. Makes my FJC feel tiny!
Tacoma is much longer of course
Took wife and kids on a ride
Kids loved it
Because they sit so far apart
Wife says best surprise ever
Can’t touch passenger
LOL
Oldest asked mpg
LOL
They are all super excited
Loving the inboard brakes
def takes getting used to
There is a ton of cool tech in these things--one day, it will be the Unimog of the U.S.
The bit that I find neat is the portal hubs get the axles higher, but they also mean the axles spin reverse rotation. So they just use regular diff units (Dana something or other?) flipped upside down... which allows them to get the driveshafts higher 
And all of the hubs, diffs, transfercase, and trans vent to a common manifold that goes to the air cleaner assembly. Nice that someone figured that out.

If you want those typelook for your local military surplus tire place. I can buy military wheels for $25 each with the run flat insert.
Man, berkeley those run flat inserts. There are few things I hate more than dealing with them
In reply to Mr_Asa :
Yeah I will go with 2 piece Oem 17s and some nice tires
looks like will set me back about $5500
Since the 20s with falken 37s are brand new (350 miles on them), should be able to get a nice chunk from sale on FB H1 group

The 4 door wagon variant is the version I would get as well.
If I remember correctly, the version I drove was the pre-refresh version (short snorkel, no A/C and the non turbo 6.5 GM diesel). It was hot, slow and loud. I distinctly remember the gas pedal was very stiff to push down. We took them through a "non-official training course" which was a 2 track trail cut through the brush on the back side of the base. That was a fun day at work 
Sometimes I daydream about buying a ratty 2 door with no top or doors on one of the government auction sites, spray bombing it and driving it everywhere with no berkeleys to give.
Yeah I dislike the convertible and I dislike the truck version. Wagon was a must for me. This has fully cold A/C.
Come and drive mine anytime. Anyting I own - any GRM can drive and enjoy while here. I have hosted quite a few GRM, and will continue to do so and spread the good karma

Interestingly the diffs are the same as AMC 20s found in the rear of 70s/80s jeep CJs and Wagoneers. HMMV had helical limited slip diffs for the brake to lock diff action.
I thought they were all 6.2 diesels for military and 6.5 turbo diesels were an option on civilian models. Very cool setup!

From what I remember, when they went to up-armor them the military versions got the 6.5L turbo diesels.
Just out of curiosity, I understand the reason for the portal axles, but what's the advantage to the inboard brakes?
In reply to P3PPY :
Come on over . Warehouse is full. Plenty of interesting things to try out.
In reply to mtnbiker4evr13 :
Interestingly the gas has more power and torque than the diesel :)
