I travelled through France in my 1984 VW camper van for a few months, developing 120 film on the go. I mostly stayed at campsites though, so fresh water was never an issue. Ten litres of water was usually enough for one batch (4 rolls of film). A van with a larger water tank would allow you to develop film on the road. I never even considered making prints in my van btw. The VW was way too small and, to be honest, I much rather spent my time enjoying the journey than going through the trouble of making prints on the road...
