I backed into myself just last May. Been years since I backed a trailer, and got too much in a hurry to let the idiots speed past on a 25mph street...
Flexed the curb side tongue bar against the step bumper of my S-10 whilst still using the step bumper ball. I now have a real 2" hitch and I am not so "afraid" of backing anymore. I simply put traffic cones ahead of time in half of the street before backing (also, my street is one-way AND inside of a school zone!)
Had one deputy sheriff (a rookie with an attitude) try to give me some grief about the cones, but then a Rice Racer came screaming up the street at 50 mph in a 25, and said rookie deputy changed his attitude.
He now sits down in the school yard of a summer evening, getting at least ten tickets a night for averages of 25 or MORE above the 25 limit. Ironically, a teacher at that elementary school got caught doing 60 the other day...
'Fession time over for now...
