I say the best bet is the VW EuroVan with a pop-top, aka Westfalia or Vanagon. It has all the room we need and a separate sleeping area so we don't have to snuggle up with steamy boot liners and stinky long underwear at night. And it's all one vehicle, nothing to tow, which means nothing for me to destroy while backing up......or going forward. Here's a video highlighting the awesomeness of the VW van.
Nikki likes the idea of a mini trailer. I admit these are pretty sweet. They're made of aluminum so we could tow it with the Suby. It has a double bed that converts to benches and a table; a small sink and a few cabinets. Nikki likes that we could store all our gear in the car, keeping the trailer uncluttered and stink free. Sorry I couldn't find a video hightlighting the T@B's features, here's a picture.
