We have here a Porsche AP18. Top speed: 20 km/h Empty weight: 1355Kg permissible maximum weight: 1600Kg. Rear brake. With permissible suspension load unbraked is 675Kg registered. But what applies to braked trailers? Approval-free trailer at the train mouth. Other question: How does it look with the 3-point field rail suspension with a ball head for a normal car trailer, is this allowed? Field rail and ball head is not allowed. Thanks already in advance. 🙂 PS: Many posts I have found are unfortunately already older. or are there very many different opinions. You don’t really look through them.
