Oh, they're pretty cramped. (As a Marine, I can tell you Generation Kill was pretty good.)
Actually, I would be more concerned about a tendency to rollover just by looking at it. When the armored ones first came out there were a bunch of accidents because they were so much heavier at the top that they tended to rollover more often.
We all had to take an off road class to drive them. :-)
Do you mind elaborating? I've ridden in the civilian Hummer, and the passengers in the back seat were so far apart they could barely touch each other if they stuck out their arms. What makes it cramped? Equipment?
Yeah, mostly stuff you wear. They're nice and comfy if you don't happen to be wearing body armor, your weapon, a pack, food for a day, camelback, etc.
Every time a door opens you see Marines and all the gear that was stuffed in there pour out. The hmmwv is spacious, but Marines typically wear at least their body weight in gear. Nothing is ever really comfortable except lying on your back or standing...
There is also the guy standing in the middle of the 4 seats, plus all the ammo boxes, brass, radios, blue force tracker (2 way gps; shows position of friendly units on a map), etc. Rarely found on the civilian h1.
I did like how body armor and Kevlar made it easier to sleep on rough surfaces (gravel, vehicles, benches, concrete walls, ...)
Rollovers were actually the number two cause of death when I was in Iraq in 2009. I've never seen an MRAP rollover, but we were always a bit edgy about it happening.
As an hummvee gunner in Iraq in 2009, we had a manual device to drop the gunner if something happened. The device was indeed used in a humorous fashion a few times. I wonder how it would be done fast enough when performed automatically to be effective.
As far as cramped goes, space is definitely at a premium, especially leg room, once you get all your gear on (and imo riding in one of those things without gear wasn't all that comfortable).
But still, cool! Though I can't help but giggle at the device meant to drop the gunner... seems like a mechanism that someone will use for pranking.
