I saw that vehicle being tested in the desert on TV. It's a really well thought out system. It can support astronauts for up to 2 weeks, allowing for extended far reaching missions from base, it can move in any direction without rotating the vehicle as well. The bubble on the front allows for close up inspection without having to leave the vehicle, and, IMHO, the best feature is the suit port which allows EVAs quickly, with minimal gas loss, and most importantly, the suit remains outside keeping nasty lunar dust out of the vehicle. I think it's pretty obvious that the developers did their homework on this job, and have come up with creative solutions that will enable explorers to explore more, and maintain less.
