Minimum gate opening width needed for TT parking........

I made sure the post on my gate was right under the eave, preventing my trailer from hitting the eave without also hitting that post. My gate width is 10 feet. I've been backing through it with a standard 8 foot wide trailer for over 16 years. It's not difficult, especially if your approach is straight. You should be able to see both sides with your mirrors. Just take it slow.

I actually have to round a tight corner, then line up with that gate with very little room for maneuvering. It can take 10 or 15 minutes.
