Look for a E350 Ford passanger van. The right combination of engine and rear end can make for a good tow vehicle.
They have been out of production for a couple of years now.
My daughter's family is close in size to yours (only 4 kids under 8). Get a Ford Expedition EL with the optional HD tow package and 3.73 rear axle. Third row will accommodate 3 people, assuming they are <150 lbs a piece !
The EL model is important so that you have some real cargo space. Not as much as a van, but more that the standard version.
