For what it?s worth, we?ve never removed the bars before backing. We have had to do some pretty acute turning to get into some tighter spots and the only issues we?ve had have come when the trailer ended up being much lower than the hitch ball, at which point it became difficult to unhitch. On those rare occasions when we were ready to leave, we hitched up without the bars in place and then hooked them in once we had pulled out to a level area.
