I've only used mine one time, for an actual flat tire. It was on side of interstate, average traffic. I wanted to change the quickest safest possible, no exits for miles. At least it was the passenger side. With emergency lights flashing, spare leaning against FW bumper, most cars moved to left lane. The big rig trucks were the bad ones, most not moving over a foot, even though most times they had plenty of room/time to do so. I would have guessed the truckers to be the most courteous It seemed the back wash was almost enough to blow the good tire off the TrailerAid. Truck jack, bottle jack, no way! Where was that LEO when you actually wanted one?
I keep mine in truck bed, while towing.
