How do you get into a Mobile?

See http://www.buckrogers.demon.co.uk/temp/mobile.jpg for a picture
of a Mobile (actually a render of a translation into .OBJ + .MTL mode
of Don Showalter's Lightwave model). How did its crew get into it?
The materials list in the file included "rear doors" in the back of
the vehicle, but it does not mention front doors. The picture whows
that it is far from clear where cab doors could be. The file gave the
name "front hatch" to some areas between and below the two panes of
the windscreen; but it would be strange if the drivers had to get in
by hingeing the windscreen up and climbing in over the dashboard -
even if it is a tracked vehicle like a tank and so has no steering
wheel.

When truck / lorry cabs hinge up, it is so that mechanics and Customs
searchers can look inside everything easily, not for the driver can
get in and out.

I read that there is a tunnel through from its back end where its
pilot gets through from the sub.

My only solution here would be to say that Interceptor pilots wear
full space-type pressure suits despite what we see on the screen. That
would be a LOT safer than an open suit with a riotsquad visor, if his
cockpit gets split open in space by enemy fire.
