This seems to me a pretty crucial thing in the UK. I had a 50 gallon tank in the boot, connected to a camping/boating type 12v pump. I started off with a little pump, which did the job, but it didn't provide enough pressure for the things I was running.
We had a full size sink, and a shower, and had bought an old instananeous LPG water heater. Trouble was, it didn't. You could have cold, or lukewarm! We bought a regulator with more flow, but that didn't cure it. Eventually we realised the real problem was the flow rate - it needed more water through it to work properly. So, we forked out for a better pump, and it all worked well.
We used a pressure switch in the system to turn the pump on when the taps or shower were operated, but we also had a master on off switch. The pressure in the system gradually ebbs, and if you don't have such a switch, you'll get an annoying whirr several times a night as the pump repressurises the system!
This all worked pretty well, and we could take good hot showers even when there was no electrical hook up. More on electrics in another thread......

To stop cycling fit a non return valve after the pump and then T in a water accumulator. We have just fit a full size combi boiler converted to lpg. The type with preheat for water was chosen to reduce water wastage waiting for hot. A powerful marine pump was chosen to give enough pressure to fill the combi and have sufficient water flow. 2 household radiators fitted but with mountings modified so they cant jump off!
