I'm kind of shocked at some of these answers here.
It takes 30 seconds to remove a draw bar. There is no need to put a draw bar on the back of the vehicle if you are not towing. Its called being considerate of others, people walk close to cars.. sometimes they don't have a choice. I don't want to be in a parking lot walking to my car, get past a truck and turn and walk into a hitch. Its easy to do and I have done it myself.
This kind of cr@p is why RV'ers and truck owners get a bad rap. We do things to intentionally create problems (pain) for others and then we spout personal responsibility and how its THEIR FAULT. Ya know that personal responsibility deal goes BOTH WAYS. Why would you want to intentionally set a booby trap for someone to bust their shins.. or a little kid take a draw bar to the chest or worse.
Please be considerate of others and take your draw bar out of the receiver when not in use.
As a byproduct, your draw bars will stay in better shape.
Thanks!
