I have a 2 dr jeep. I tow with a Currie baseplate (replaces the front plastic valance panel with a steel one; $200, easy bolt on and hell for stout. Having seen some "professional" jobs, I took my chances and did it myself), a Blue Ox tow bar, and a Brake Buddie. I used the CoolTech wiring harness for the jeep lights, which almost installs itself, plugs directly into the Jeep harness. takes maybe 5 minutes to set everything up. Getting the baseplate and wiring set up was an easy half-day job. Personally, I think the Blue Ox base plate is overpriced and flimsy compared to the Currie (they make the Rock Jock line of skid plates). The Blue Ox towbar, however, is a gorgeous piece of machinery, worth every penny when trying to hook up in a snowstorm.
The Brake Buddie is a pretty simple device, there are more sophisticated systems out there, but it's certainly easy and relatively inexpensive, and has the additional advantage of being easily salable if I decide to go with something else in the future.
