I like the hearse up above, you could paint the logo on the side "Death From Above"!

Minivans are great and most will pull a small trailer without probs, full-size vans and pickups can pull more trailer and hold plenty too.  If you go to fly-ins and need to camp for 2-3 days don't forget all the camping gear too! 

We're up to 12 kids now so are stuck w/ a full-size van and trailer and usually one of the older kids will drive a pickup with another trailer w grill/ dirtbikes etc.  We stopped thinking about gas economy a long time ago and every once in a while a city representative stops by and reminds us to get trailers/vehicles off the lawn! LOL.
