Oh! Thought it was just us using doggy bags. Our van has a nice fitted thetford, but after years of emptying the darn thing, once we found some where ok, we hit upon the idea of using a 1kg yoggi pot in the bowl with a perfumed doggy bag in it. Can't really trust this set up for number ones, so we use a stash of suitable bottles securly stored. And yes girls can do it too, peewees work a treat. Keep some suitable disinfectant in a spray bottle handy, we use the pink stuff. If in one place for a while where you can't mt the bottles, the more the have the better. We have a very good extractor fan in the bathroom, pretty much essential.
