As a owner of heavy equipment, the only thing that bothers me is that he's heating up the steel on that $40K-$100K bucket. BUT, since he has water in the bucket it theoretically shouldn't weaken the steel. If this guy is up in the middle of the Yukon or Alaska mining gold or whatever, I could see it, but I'd never do it because i would of brought a f**king RV to shower in, not my excavator bucket! If he's one of my employees, I'd fire him immediately! Equipment like this is simply too freaking expensive to do shit like this to! That's my thought on this.
