Then you definitely need to get some practice in beforehand. As someone suggested, go to a deserted parking lot (I used the local high school's this summer) and practice turning and backing. We discovered that I (not DH) was best at backing. It may be that you won't need someone to actually back your unit in, but just to give you some guidance while you do it. It is much easier to get someone to spot than to back in, even though I don't think that you would have any difficulty in doing either.
I think going on this trip actually sends a healthy message of strength to your daughters. While it would be understandable that simple grief could prevent or postpone your trip, it certainly wouldn't do to imply in any way that "the girls" can't handle this without a male along. I think going on this trip will help them see that while we women love having the guys along, that sometimes it doesn't work out that way, and having a male presence it isn't essential to being able to make the trip.
Good luck with everything.
