mine gets driven to/from work one day a week (75 mi each way). occasionally it takes/picks up the kid from school (about 1. 5 miles each way). Otherwise it sits in the driveway. I've only had it just shy of a year (used, its a 99) but it's been on a few 750-1,000 mile trips empty and one 2,000 miles trip with 11k behind it. So far, about 9,000 miles on it since I bought it last Nov.
My other truck is parked in the backyard and that gets driven 1000 miles per year, maybe. So far this year its done 558 miles. However, this one is a gasser and now barely street legal.
