Ive hauled at least a dozen games in my 2008 xB.

Every standard size pin ive tried has fit, even giant Gottlieb system 3 machines with the head still attached. Fitting a machine with a separate head is a snap, but bring plenty of moving blankets/cardboard to wrap the head in so it doesnt get all dinged up.

A Superpin wide body will fit, but I dunno about a bigass Bally like Paragon or Future Spa. Those have a massive back end.

Also! I have never been able to fit a pin and a dolly at the same time. You might be able to get away with this if you put the dolly on top of a headless body, but theres not enough room on the side for one. At least not the two dollies i've tried.

I put the head beside the body, angled a bit so it cant wobble about. There's not quite enough ceiling clearance to put it on top.
