That looks really neat, looking at it makes my micro-unit feel all tingly! But then I'd have to get a different license class rating, and actually have to learn how to drive.
Perhaps this is more practical; and you know I am ALL ABOUT practical!
Just put it on one of those Diesel truck flatbeds from Ice Road Truckers. This way you could have a two-stage "thrifty-mode" where your image-dump-truck will be getting infinite MPG with the engine off while it's on the flatbed (you'll need a GPS to credit the MPG, since the odometer won't move). When you get to your destination, you can go 4-wheelin' in the mall parking lot in the image-dump-truck with all the gas you save (about what, 30 seconds worth?!?!?).
Apparently I missed an interesting exchange from this afternoon on a now deleted thread. You guys have all the fun! If thats not the case my suggestion is a "turbonator exhaust" they have excellent swirl production properties.
Edit: My bad, I thought the range rover thread got axed
