Good morning together! For a long time I have been dealing with the purchase of a used caravan. (Was 20 years on the road with tunnel tent.) On the weekend I looked at a Wilk s4, in which I noticed two things that I find strange. Ventilation hoses: The slots in the ventilation hoses, which run in the stowage boxes, are all glued off with silver colored tape. I always thought that the slots in the hoses were not a mistake but absolutely Is this normal or has it been improved there? Outside ventilation grill: The caravan has an oven (as for me superfluous gimmick) installed. With caravans with oven I have noticed so far that these three ventilation grilles have outside. Twice for the fridge and once for the oven. This caravan has only two grids installed at the height of the cooler. Also here the question is, is this a possibility or rather a mistake…. a good start to the week
