Why wouldn稚 they just drive it? With those big off road tires I wouldn稚 think the ground pressure would be that bad.
Until they get to the first overhead object. A signal light or overpass a sign and that would be as far as they would get.
They have a couple other similar pictures on their website, one of them shows a Caterpillar 793C (just the body, no dump box) on the dual trailer setup (which they claim to have invented).Would expect a maneuver like that to be staged.....carefully staged. But it doesn't appear to be fake.
Looks like it may be this outfit:
