Backing up to an inclined and narrow driveway

It sounds like a similar driveway to ours. We have a 25' TT that I back into an 8 1/2' driveway that's cut into a hill. My biggest issue is the hill and since it's cuy in there's no room to swing the trailer once in the driveway. It took some trial and error to find the best way to do it, but isn't too bad now.

Here's a video of how I do it.

The good news is you likely won't find a site in a campground that hard to get into.
