Portable toilets for drive in, or maybe packing, but drive in mostly.

[skeptic]

Since my camping is now restricted to drive in sites, or ones we can drive easily to anyway, but have few or no facilities.  Water is often needs to be carried in so cal, and some campgrounds do not have serviceable toilets, or enough for larger crowds.  But there are a lot of more remote spots that do not have any at all, but you can camp there and fend.  As a well seasoned person, I no longer deal well with  the needed process, other than peeing in the buses.  My family has a five acre plot in the desert that is on the edge of Joshua Tree, but we do not live on it, and we have not put water or electric in either, though the kids may at some point in the future.  But, I take the group out to my house on a third acre and we deal with one bathroom and portable urinals, but if we want to use the acreage, it has no facility.  I was looking at available portable items and note they are not too expensive for the basic needs.  Does anyone have any thoughts or experience with these travel potties?
