Most definitely.
Ritchie Bros occasionally has some really good deals since most buyers at their auctions are there for construction/farm equipment.
Only thing I can find wrong with that bus is that it has Peterbilt wheels on it.
I'd think that with the interior already set up the way it is, all you'd need to do is rip the benches out of the back and build a bedroom, and add a shower. Pretty quick and easy conversion. (I'm assuming it already has hot water for the sinks and some kind of small fridge in the bar/kitchen section. edit: Oh, and add a stove/oven/something like that.)
