Backing into my storage spot

[rosede]

I have an Outback 272RK, overall length is 30'.

My storage space is 12' wide. I have a large fifth wheel on passenger side, and a smaller camper on drivers side. The space in which I have to back into the spot is very narrow.

My question is; how sharp of an angle can I use to back into my storage space? When I back in, I currently don't make to sharp of an angle because I'm concerned about putting a strain on the frame or tongue or something. Because of the two campers on each side, and the narrow area in which I have to negotiate the turn, I make at least three attempts to back into the spot. I'll back in to a point, pull forward repositioning, back in a bit more, pull forward repositioning some more, then finally fully backing in. However, if I can put a sharper angle on the turn, I should be able to do it in one full turn, or at least cut down on the number of times I have to pull up and repositioning. But as I said, I'm concerned about putting to much of a strain on the frame or the camper. Any thoughts?

Thanks.
