Toilets

I know lots of you have a toilet of some sort either in you trailer or a pop up tent or a side curtain But how many of you actually use them I was thinking of putting on in my little trailer that I have started but they take up serious space and no matter how I do it it seems like it just gets in the way ..to close to the bed to close to where food is prepared to close to the door(don't want strangers staring) so if you use it where do you keep it and what kind do you use as I was thinking of making a sawdust toilet but then my friend tonight brought up a good point so your going to haul your "poop" around with you?...Now what do I do?
