Hi Sidewinder,
Whether you have the hitch [AT35 or Hyland] on top or underneath the A frame's plate is determined by the height of the tow hitch on the vehicle.
Our 18' and Patrol with Canadian(?) HR hitch receiver needed the AT35 under the A frame plate to get the vehicle and caravan horizontal when coupled and load bars fitted.
When a 100 LC replaced the Patrol, the AT 35 had to go on top as the hitch receiver "socket"on one vehicle was slightly downhill and on the other vehicle it was slightly uphill - had to look closely to see the difference but it effected the vehicle to van setup.
When the Hyland replaced the AT35 I tried the Hyland both on top and underneath but the best, for us, was with the head of the hitch [the bit which goes into the hitch receiver on the vehicle] having the longer leg upward to avoid ploughing bitumen on steep kerb crossings, and the Hyland mounted on top of the BT's A frame plate.
Yes, we always use load distrib bars and the only problem is that at extreme angles or sharp corners the bars "graunch" against the bottom corner of the A frame.
Cheers from Martin B currently in Boulia Qld.
