Now, do I post a prototype of a huge big heavy thing that you can’t buy yet or an M274, which is a kind of chassis-only truck that the US Army used to use?

Oh, let’s go for peace.

Have a Liebherr TI274.

3,000 bhp, 170 tonnes empty and can carry up to 290 tonnes.

Somewhat surprisingly it can top 65kmh/40mph. How you’re going to stop 460 tonnes from that speed is another matter. Don’t get in the way would be my advice.

How you stop these is with oil cooled brakes and turn the electric motors into generators and run that electricity through a giant resistor...that's how you stop them

I’m still getting well out of the way.

They are sort of oil cooled, but really what's going on is you basically have a clutch pack (like what you'd find in an auto transmission), and the hydraulic pressure compressing the discs is what happens.

yup, and that generates tons of heat that needs to cooled (especially if they are fully loaded and making an emergency stop)...the oil does 2 jobs in the brakes for these things

Just clarifying for those that may not have known that off-highway equipment generally uses “wet" brakes.

Man I bet you could turn that thing into one hell of a camper van.
