I've never heard of these, I wonder what other nifty stuff they've come up with.
Electric motors on all six independent suspension wheels.
Turbine powered, pretty cool.
Solar 10MC turbine

Put it in low, go take a dump, the ultimate convenience.

But....I didn't see any cup holders!

R. G. LeTourneau was a very prolific designer and manufacturer of specialty machinery as well as production heavy equipment. His facilities in Longview TX ( now owned and operated by Komatsu, a separate steel mini mill is now operated by Nucor) were unique during his life and times. He was a early builder of offshore oil rigs. He founded LeTourneau University, also in Longview.

Same guy did a good presentation on R. G. LeTourneau.
A forward thinking guy for sure.
