Backing the tow vehicle to the hook

[BW from AZ]

Practice..You'll get the feel for it..Get the trailer and vehicle in a dead strait line and look in the mirrors, you should see things about equaly spaced. Sneak up on it.
All good advice. I might add to lower the hitch a turn or two so it touches the ball and not the bumper or tail gate. My suburban will squat 1/2 inch and slide under and then pops up when i do it right. I'm called back up Bob by some of my friends .
