Yes I did have to unhitch but to be fair that wasn’t the issue as I got it down to a T and was off/on in seconds. The main issue was most service station charging stops had me drive past the chargers to the caravan parking. I would then have to drive either all the way back around, or in a couple of instances drive back the wrong way down a one way. However, twice I found charging stations the were trailer friendly. But that was two out of probably 15-20 stops! The infrastructure certainly needs improving.
