I've slid on ice while carrying around nearly 3,000 gallons of liquid pressurized propane. That gets your butt to pucker.

I worked yard and now work office around propane, I fucking bet.

When I did diesel driving in a smaller truck myself and about 1k gallons of diesel slid down ~160 ft of mud bill because some jackass left their fucking throw mat out before the rain started, it cmgor covered in mud and when my tire hit it I lost all traction and shit went literally sideways from there

Scariest however many seconds that was in my fucking life, I realized almost immediately I had 0 control over what was happening until I hit some flat land, which I prayed gave me enough time to stop before going over into the dry riverbed, likely flipping

It's all good, I hit a rock at the bottom going about 15mpg and put a big ass dent in my bumper is all!
