Let us all admit it the bloody things are too heavy with all the poncy bits the makers put in. They could be a lot lighter with decent design. My Chauson is plated at 3860kg but to get it down to 3500 requires no waste water a full tank on fuel some bits of clothing some food and leaving Maureen on the road side. I would make her get out stand away and weigh it without her if it was weighed officially if they did not notice. However at the higher weight all goes in and a motorbike, but I will not be able to drive it after 70. All the various makes seem to be very heavy in construction, loads of chipboard does not help and a floor of 25mm + plywood. must be scope somewhere to make them lighter in manufacture.
