What do you pull your cars with?

My experience has been that the trailer is as, or more, important at the tow vehicle. I've pulled trailers that seem to want to take you all over the road, some that are a bear in wind and some you hardly realize there's a car on a trailer behind. Most of my pulling has been with a W150 Power Wagon w/360, a 2003 Chev 1500 4wd w/ 5.3, and a 2005 1500 RAM WITH 5.7. The pickups all worked well.
