Probably my 06 Scion XB is the ultimate gig rig. Plenty of head room, seats fold flat to hold all gear, 34 mpg, totally reliable.
However, I now use a Ford Exhibition, or I did before lightening hit it in early December. I'm supposed to get it back possibly tomorrow. Meantime I haul my gear in the back of my "fishing truck", a 97 Silverado with tonneau cover. I don't drive it much because it is in nearly showroom condition, with lots of custom stuff. I have a sound system in it that will rattle windows for blocks around, with Johnny Cash music of course.
Trivia--they didn't make the XB in 07, then changed it a lot for 08. Bigger Camry motor, less room, less gas mileage, less box-like. Too bad!
