I had a Passport 3220BH(37 ft bumper to hitch) and was able to get in and out of some tight spots. The main downfall from tight maneuvering is the side load stress put on the tires.

Having the ability to use your neighbors driveway is a necessity from what I can tell using your sketch. My first question that comes to mind is what if your neighbor changes his mind or sells his house in the future.

Would you be able to back down the street and into your driveway? That might be a second option in the event your neighbors doesn't work out.

Just my 2 cents.
