———————————————————————————
In the pre-electric days ( the dark times) we used to plan routes based on KM/day
Stopovers at small hotels .
Since we now have a hybrid, we would at least start every day with our 50 to 60 km electric.
Our charging capacities are only 11 Kw/h so it is only during luchstop, and sleepover that we need an AC point
