We are gradually getting to grips with this vehicle. The water tank, which fills all of the space under the kids' seat, and takes about ten minutes to fill with my Dad's garden hose at full blast, only seems to last a couple of days' modest use.
I filled it a second time using the AIR AND WATER machine at a BP garage near Lowestoft, which cost me about three quid in tokens and cramp in both hands, but seemed to work in the end.
The toilet cassette, likewise, demands attention every couple of days, despite a whole-family commitment to keeping Materialisations of The Brown Lady for special occasions. On the suggestion of some bloke on the Internet, we've been using biological washing machine liquid instead of the blue stuff that is designed for the job, and the jury is still out on whether it is as effective.
We've done another three nights without paying to camp. The first was in a council car park at Overstrand on the Norfolk coast, a gorgeous cliff walk to, and beach walk back from, Cromer, which is a much nicer town than one might ever have guessed from the expensive campsite of lost souls.
The next night we drove to Knettishall Heath in Suffolk, en route to pick up a few eBay essentials (mains hook-up cable, another USB power bank, and a charging cable to connect this to the kids' 3DS) from my mum and dad's. We spent the night in a secluded muddy lay-by, and the nice fella who informed us the next morning that we are "not really supposed to" camp on the heath seemed to accept that there is very little that can be done to make the policing of it possible, and that even if there were, he certainly isn't being paid to do so.
Last night we were as comfortable as we have been so far in a tiny cul-de-sac in Cambridgeshire. This was obviously all in the head - the fact that M's mum lives in one of these neat little bungalows wouldn't have made any difference to the way that passers-by looked at us, as nobody knew who we were, but we were confident in our right to be there. Maybe this frame of mind might serve us just as well when it is erroneous, too?
