Adjusting split jambs on pre-hung door units

I know that if my door openings are too wide for pre-hung units I could always rip some jamb extensions, but what should I do if the rough openings are to narrow? Is it relatively easy to rip the jambs down, or do split-jamb units built with a little wiggle room?

are they thin enough so that you can put a rabbit in the trim work and over lap the door jamb?

I'm not sure about the exact measurements yet, only anticipating the problem (I think no one read the instructions when they built my house). Rabbitting the trim seems easier than ripping the jambs, though. Thanks.

They are designed to accommodate nominal 2x4 studs and 3/8 to 5/8 drywall.
