We had it on the tow ball of our California 5.1 SE and we thought there may be a problem at Eurotunnel if they want to check your gas bottle tap…However we found that by releasing the bolt the rack could tip backwards and the door could be opened although it was a bit close…We only had a couple of small bikes on and had twisted the handlebars away from the back window….Not sure on a Cali T6 as they might be different…You are welcome to try it for size…presuming it’s not too far from you, or alternatively see if anyone on forum has the same fitted…cheers
