- Action Mobil. Their most impressive vehicle is the 8×8 Desert Challenger.
- Bimobil. Their vehicles are based on Mercedes-Benz trucks whereas many the others in this list are based on MAN trucks.
- Bliss Mobil.
- Krug Expedition.
- Global Expedition Vehicles. This is a U.S. (Missouri) based manufacturer that uses the Mercedes-Benz Unimog platform.
- Sportsmobile. Mostly van conversion.
- VARIO Mobil. Not really expedition-class, but built on Mercedes or MAN trucks.
On Bliss Mobil’s website, there is a handy chart for estimating the amount of water consumption:
Bliss Mobil seems to specialize in manufacturing the “box” portion of the RV, as can be seen in the video below. It is a nice idea as it is independent of the underlying truck platform:
Earth Cruiser (based in Australia but with a subsidiary in Oregon) vehicles are much smaller but seem well-designed:
Earth Roamer’s vehicles are based on Ford trucks. They look like camper-on-pickup-trucks, which is not the style that I like:
So far, the ones based on MAN (VW’s truck division) chassis look best to me. They allow the driver to sit high and without a big protruding engines to enable better visibility. They also seem to be designed with much larger departure angles. Looking at the Ford-based vehicles from Earth Roamer, you can see how the back wheels are much farther from the rear end of the vehicle, which is not angled upward. I would hardly call 23-degrees of departure “off-road”. Compare that with, say, Unicat’s TerraCross 59:
The following spec of Mercedes-Benz Zetros offroad trucks:

This Unicat 4-axle 8×8 is my dream:
The Unicat 8×8 is as tall as a double-decker coach bus, as long when the rear slide-out is extended, and slightly narrower. I wish it were just as wide or even wider.
