MONSTER TRUCKS

OK, I understand how it is that a guy in a truck with the $1000 special lights package--running lights, fog lights, deer lights, spot lights--can't seem to use the turn signal.
I get that.
But how is it that a dude in a 2500 series-- monster tires, diesel engine, super shocks, ranch hand with winch, titanium rear end and dually wheel wells-- cant go more than 1 MPH in the apartment parking lot, practically comes to a stop at the speed bumps, and makes every effort in the world to maneuver two of his wheels from touching the speed bumps?
Am I missing something here?
