Hate to sound like a stuck record, but as per @Savage1 s comments, go review John Cadogan's YT channel on towing 3.5T in Aussie: In essence DON"T!!
If your caravan actually weighs 3500kg, all full of goodies, you'd better have one skinny wife and no kids, otherwise you will be over your GCM. In Aussie the highway police will ream you for travelling like that, and sticker your wagon.
