HI Eribanut
We bought it new through AL.
Being lifelong tenters we had no experience of caravans and were very naive. The only caravans we had been in before purchase were friends all-singing and dancing big white boxes.It just didn't click that having the heater attached to the warm air vents would be an optional extra - we should have thought Audi and BMW, cars as our example not our Skoda Octavias.
We don't attach any blame to AL as they spent so much time with us before, during and after the order, especially Cameron.Our simple logic was if there is a heater provided and warm air vents fitted they would somehow connect. Should have paid more attention to E.M.Forster "Howards End" when at still at school!l!!!!!!!!!!! MikeT
