Looks like a good job, including strapping the bed to the cab.
The only thing I wouldn't do he did, is having the antenna outrigged like that (outside of the bodyline).
Being a klutz I'd probably be running into it. And it would naturally "catch" things first.
I'm not sure why he has to change coils on a screwdriver, I mean I put a coil across mine to bring the impedance down on low bands, it's not the most optimal but did allow a low SWR by the autotuner. this was when it was in my car, have not put it in my truck yet.
They HANG antennas in THESE here parts!
