Snowmobile?

I’ve seen these on Suburbans before, but never on a Land Cruiser. Looks strange either way.

It must put tremendous strain on the steering system.

Crazy to think that this all came about while a kid was playing with his toy car, and decided to strap the body to a toy tank. And from there this is what it turned out to be.

I've seen these being demonstrated before and as gar as funtion goes, its a good thing, but its looks odd.
