I tried once to pull without my anti-sway bar in place. DW had taken the truck to get some groceries before I could retrieve the pins for it off the back bumper and we had lost them. Well, 20 minutes down the road I was pulling into a Meijer's to buy a new set of pins. No way am I ever pulling without one again.
i don't know your setup, only you know that, but look at this way. What's safer, with an extra safety feature, even if it's overkill, or without?
There's no use crying over spilled milk, unless it's on your keyboard.
