Stop in for a cup of coffee

That's a whole lotta crane for a pickup truck. If he never run a crane before, get close as you can to the job, keep the boom as vertical as possible, heavy loads straight off the back, careful swingin' over the side, keep load close to the ground. Power lines overhead, watch out for them, you don't have to hit them for them to hit you.
I have had a crane license for years, only good to 100T tho. No big boy cranes. It can get spooky very quickly, and most all of my dumb stunts were on smaller jobs where general contractors would stretch capabilities and applications. I always post one of my riggers on the back side soft foot with a radio. I tell him you see so much as a glimmer of light under my pad you tell me ASAP. Everything is fine right up till it is not on a crane.
