We used to do dry all the time in the tent trailer (it had full shower / toilet as well).
In our 21RBS we have been using hookups more, but, are now leaning back to dry as we got it figured out now for our Weekend getaways.
Propane, just filled a tank, can't remember the last time (not last year so...), and there are 2 up front, so, this is not a limiting factor.
Power, we have an 80 folding solar panel, even running the furnace over night, this will give us a full charge each day, so this is not a limit (remember, no AC or Convection oven).
Water, one full tank, 2 people, 2 days (with showers). We also have a way to add water from buckets, and drain gray, without moving the trailer, so we can extend this until black is full (about 5 days, but by then, you want to dump that anyway )
Give it a try.
