4-wheel drive that has a lift kit. I have a CB installed in all of my vehicles (except the newest, it will get one before next spring).
CB is still superior to cell phones or even hand-held "talk-about" FRS/GMS radios when it comes to vehicle-vehicle communications.
If you ever see a 2500HD pulling a trailer being followed by a Land Rover Discovery 2 or a Hummer H3, say hello. We're on channel 13. .
