If you can get a pull though site for your first site, that would be ideal. If not, or whenever you do need to back in to a site, forgive each other beforehand for any cross words that may be exchanged and pledge to be as patient with each other as possible.
Maybe have the kids take the dog for a walk while you park the rig. We have been doing this for a while now and it can still cause issues at times. We very nearly had to give the rig back the first time we tried to back it into a spot at the storage facility.
The rest of it is worth the grief it takes to get into that awkward parking/camping spot.
