Which part of the county are you in Ian, where do you park the car overnight, I read you don’t yet have a home charger?
The last two weekend we did 465 miles each way to see our grandchildren, In one journey, only stopping for a sandwich and loo break, I did notice all the charge bays were full on the M6 services and my wife commented good job we don’t need to recharge.
Both trips we made the return at night or early hours of the morning with main beam on unlit roads, I’d be forever thinking we’d run out of juice.
