Al, I'm bringing so much stuff that I'll be driving a truck and will be pulling a trailer with a box on it to keep everything out of the weather. Heck, the last time I was down there there was 1/2" of ice coating everything even before I left Arkansas! It finally got better the closer I got to Dallas, but only because they had time to get the roads prepped.
No way would everything fit in the car, and there's a bit of wind drag with the box on the trailer. Also, I don't know exactly what some of the roads will be like (I'm pretty sure I'll be on some non-paved surfaces) so the 4wd might come in handy. (there's still room for the chipper on the trailer......)
