Thanks.So far, my plan has been to use locations I am happy with. Just as I plan my approach to a CL using Google maps, so I plan my charging. Classic services are not so good for the exact reason you state. Supermarket chargers (rapid) are good as you can often find lots of space in the carpark for the van. Leaving the car unattended while charging is fine. The van we tend to always leave with at least one occupant, while the other(s) shop / use the loo etc. Very similar to a motorway services type stop. Some places are better than others. Duckmanton M1J29A and Skelton in Leeds - both excellent. Lots of chargers and decent sized car parking.
