The Ford E series or Chevy vans would work, but just keep in mind they aren't really built the same as most passenger vehicles. They are designed first as commercial vehicles, and are very crude on the inside. For some people this isn't an issue, but if you're expecting the same comfort as a modern half ton or 3/4 ton truck, you'll be disappointed. For my work we have had about a dozen different E-series and Chevy vans over the last few years. Currently we have 4 E-350s, and 1 Chevy 3500, all diesel except one E-series. They are easier to drive than you expect, but also noisier than you expect. The fit and finish of the interior is also lacking significantly. Our 2011 E series has the same steering wheel as my Grandpa's 1997 F-150.
