Potty ?.+Updated.. Read again if you.read it already!!

I can't fathom any situation where a toilet over a hole in the ground is acceptable, except a properly designed vault toilet. Not anything you can manage on a temporary basis. That would be extremely obnoxious and unsanitary.

If you want to set up a temporary outside toilet, get something like a "Luggable Loo", and use it plus a privacy tent, with appropriate bags to contain the waste.
