Looks like future proofing, but possibly some hybrids will use them first, although many of these will sneak a few amps using a plug on the caravan if they can get way with it. You really only need the full charge for a pure electric.Here’s a weird one, or is it? South Meadows , Belford , Northumberland, are expecting lots of tuggers who need a recharge🤪🤪.Good on them but not sure what cars are doing the tugging???
