Hi Ron
Fantastic post – backed up with a lot of pics and facts.
I do how ever disagree with the bit up the top on boats, I have not towed a caravan, but have towed 2.5 to 3.5t boats extensively along the QLD coast, and my experience is that it is absolutely horrible to have a trailer load that is balanced especially if it is significantly heavier than the tow vehicle! Yes the draw bar is really long but talk about the see-saw effect (up & down and side to side). Even most of the top boat trailer manufactures now recommend 10% of total mass as the ball weight. On the rigs I had I shifted the axle frame (they are all adjustable) to give close to the max ball weight up front – then learnt how easy towing is with the Reece kit.
There’s a club ex Melbourne that tow (mostly) 7.0 & 7.3m Whittleys (around the 3t) all over the place – I met up with these guys on the way to the Whittsundays a couple of years back and no surprise – they all use LDH set up and swear by it.
