I'm the guilty one with many cars (trucks, actually). As follows:
1 2006 Ford Diesel Pickup (DH's work pickup)
1 2002 Ford Diesel Pickup (4 door, it's my baby. and it's paid for this month. whoohoo!!)
1 2000 GMC Yukon XL (it's big and comfy, seats 8, and sometimes I need the two extra seats when I have extra kids, like my SILs stayed with me for a week while MIL was in the hospital. My 4 kids completely take every seat in my pickup. But, I need my pickup to pull my camper and horsetrailer (which are gooseneck, meaning they hook up inside the bed of the truck, not on the bumper. So no getting rid of my baby. heehee!)
1 1986 pickup (the feed truck. For feeding cows and fixing fence. It has a big box on the back for holding and distributing feed without ever leaving the cab. A good thing when there is a 2000lb bull right by your door)
1 1994 Freightliner semi truck. for hauling hay, seed, some farm machinery, etc.

Also have 2 tractors and 1 swather, but I didn't include them in the survey.
