All this talk about the truck, I should probably explain how we are powered. There’s enough sun around that we could/should be solar-powered, but we aren’t. Instead we carry 1500 litres of diesel. There is a main tank and two auxiliary tanks. The first big fill (in Ceuta which is in North Africa, but considered to be part of Spain) took more than an hour and cost a fortune in euros (see photos). We have ‘topped up’ several times since then, but no fill has ever matched the first one in terms of time and expense.
