Hi Andy,
No, one lives in a coach house. One has no garage or means of storage, pretty similar to the 3rd coming on board.
I've recommended steering clear of in van production only, as you're then limited to the amount you can use each day. I went down that route when I first started out and soon got fed up of running out of water, with no quick way of topping up.
I currently have 2x 1000ltr ibc's but they are taking the strain even between 3 of us with the current 450gpd unit I have. Pretty much bone dry by the time we finish each week.
