I love watching those who know how to backup without assistance do so going back & forth, getting out of the truck then back in again multiple times while the DW attends to the itty bitty dog & the traffic backs up on the CG road as Mr I Can Do It gets frustrated.
Great entertainment. Watched one once. Counted 18 times forward & back getting into an easy backin.
I'll stick with the DW using a radio, giving simple hand signals & acting as a reference point for backing in. Boring to watch I'm sure but we get into some crazy tight spots without drama.
