We’re time served caravaners and looking to buy a second hand Swift 570 now our kids are up and off. Our last Swift caravan had Truma heating and a fire but we notice there is a crossover with the newer moddles where they stopped putting fires in them. Can anyone with the newer model Swift tell me is the heating good enough in them without a fire to initially blast the heat when you come in from the cold. I’m guessing the heating is more superior in the newer models so they don’t need the fire so much but not sure if people think it’s better and I can’t find it on google anywhere. Thanks ☺️
