Here's a story revealed a few months ago...but, it was the most recent "news story" I found to post...

The lead:
"That's cool, but you're never going to sell one." It's a sentiment that EarthRoamer, builder of some of the world's toughest off-road expedition vehicles, has heard many times over the 12 years it's been rolling product out. But it has sold them, 150 of them, in fact. The company is so confident that it will keep selling them that it is now working on an even larger, more expensive 4x4 motorhome. We previously took a look at the basic specs of the all-new XV-HD expedition vehicle, and after traveling to Overland Expo, we have a few more details about this beastly build, including its near-seven figure price tag.
