Ah, the insides of the Mushroom Tours bus! Took me a while to work out what it was. Do you think it is a real bus, like the van in Thirteen and possibly the jeep in Katanga Canyon? It does look like it.
in Katanga Canyon is not a jeep actually, it is a Landrover Series 3, Long Wheel Based, Safari edition, and not because of the paint job no, but because of the fact that there are windows in the very "back" part.
There you go a real one in action. BTW I actually own one of these personally so yeah ... Get it right Bill!
I can't find an image of the bus, but it is also a real vehicle, but I can't remember for the life of me what it is, like Ripsaw's control cabin is a modified I think is an old Bedford but am not 100%. And the crashed van in the Th13teen queue line is a Daihatsu Hijet.
