Interesting, I've always thought that a 4x4 van with a pop-up would make the best camping vehicle. A Sports Mobile is on my short list of ultimate camping vehicles. I recently test drove a Ford E350 with a 4X4 conversion made from the front end of an F350 truck. That van has since been sold.
What does your conversion cost? I would like the fun of building my own interiror, but do you offer interior builds other than the pop-top?
Holy Huge Tent Batman!!! That has to be the biggest pop top in history. I love the space up there, it would be great but how does that do in strong wind?
