Update. We decided not to change the Triton for the troll back in the Sprinh as we had just bought a house. However, having not used the van at all this year and then trading in the car with newly fitted towbar leaving us at the moment no towing facility we had asked Jandi to collect it for its annual service. (It’s only stored a couple of miles from them). Anyway, the still had the Troll available so we’ve only gone and done it. I guess it will be the spring again before we actually start to properly get our head around this caravanning lark.
