All the time!
We keep the porta-potti in the trailer for night-time nature calls, but have put it outside during the day so that the kids can romp inside the trailer.
I personally like the Big Cabelas privacy/shower tents. We have a little one that was a gift, but would love one of the big ones that our friends in the military were able to have FPO'd to them.

This one is like the one my friends had. It's nice and big. Theirs was from Cabelas, I think.
