For nearly 23 years our family camp vehicle was a 1986 Toyota 4x4 pickup.  Since 2011 it's been a '99 Ford F-150 4x4, but this past week we broke with the truck tradition and decided to go small.  My wife's work car is a Kia Soul, which has a ton of room inside and has proven to be more than reliable.  I fitted a basket on the roof and we packed gear as though we were doing a moto camping trip and it went beautifully.  32 MPG didn't hurt one bit either.
