Between rear and front wheel drive, it's really not viable to use a rear wheel drive unless you don't plan on ever exchanging an empty cell... or being pushed into a corner. That portion is carpeted and if you use rear wheel drive to get there, you're going to end up with the front wheels on the carpet with high traction and the powered wheels on the regalith with low traction, making it incredibly difficult to move. And backing into the corner wouldn't work either, there's a trailer in the way.
