I drive an '83 ford van- Moby Ford -with a 302, automatic, air (which just died) and seating for seven. Take out the rear seat and I can carry the full p/a for an 8 piece band plus three passengers.
It's old, rusty and utterly reliable. I can sleep in the back if I put the p/a and instruments in the trailer (covered and lockable). The down side?
The gas consumption is frightening.
Memsabib has a Geo Metro 3-cylinder which gets 45mpg. When we don't need the p/a, we drive that.troll
