I always liked 5-wide vehicles, I loved the Army Men from Toy Story, and the frame I had sitting on my table with Legohaulic's Steering Technique was pure fun to play with. This mod of 7595 is only the logical result.
The steering system did necessitate some changes to the Jeep. Notably the 3-wide wheel wells and raising up of the whole chassis a bit.
The decision to go 5-wide with this vehicle was mostly personal preference, and I originally wasn't going to do it because I don't have a ton of green plates in odd-numbered dimensions. After I did a 4-wide prototype, however, the Jeep just looked too elongated. Making it a stud wider solved that.
One of the benefits of going wider is that the Jeep will now comfortably seat multiple soldiers or (as pictured) a soldier and gear in/on the back. It still can't seat a second minifig in the front, though.
