Since this place has kinda blew up recently, not sure if this was posted or not?
There was a hint in the early photos of the new support trucks that RGM added the 2nd set of doors to the cabs, just cool! The 'pop out' was a nice surprise in rally pics.... hydraulic steps... cush, man, just cush!

... Upon arrival at scrutineering , other teams and competitors in the Dakar Rally were amazed by Team HUMMER's Freightliner support trucks. This was the first time that the public have seen them up close and personal. The support trucks are significantly longer and lower than the standard chase or support truck. They feature 4 doors on a Freightliner cab with hydraulic steps, leather seats, King off-road shocks and air suspension. With the massive support trucks and HUMMER H3s parked outside of the convention center, fans and competitors alike all stopped to take pictures.
