It seems wrong to me that it is not mentioned anywhere that the first pioneers of such suspension / suspension in the MAN truck at 4:40 were invented by the Czech carmaker Tatra in the first half of the last century before all others. If the Third Reich had not violated the Tatra patent after the occupation of Czechoslovakia, the Tatra would have been even more respected and recognized in the world than it is now......
Tatra has also been producing cars with this and even better suspension for decades, unlike MAN with the Rheinmetall HX 10x10
I am also proud that Sleipnir is from our Czech company Tatra.

I want to build a train truck. When I mean train truck, I mean a truck that pulls a few trailers like a train. It would have 800 HP quad turbo inline 8 engine with 8x8 drivetrain, 8 MPG city 11 MPG highway, crew cab+sleeper cab, off-road capability, both truck and trailer have cargo options like: dump tipper, container, flatbed, tanker, camper, car carrier, passenger, etc. Top speed of train truck: 74 MPH. Acceleration 0 to 60 is unknown. Weight is unknown.

This is a video about offroad capable trucks... so why did you not mention any technical specs of the trucks, that make them so offroad capable. Not a single word about chassis, suspension or engine! Only exception is the Toyota Coaster bus.
