Couple quick thoughts are:
Get a tongue scale. Sherline a great product for tongue scales (try looking it up). This is a great product for trailer shopping as well as for loading.
A 23' box with a tongue weight over 600 LBS seems high. Often a particular floor plan can be found by another trailer manufacturer with either light weight construction or a slightly different axel position which can change tongue weight drastically. Ultralight versus a stick and iron trailer will demonstrate this best.
There are several WD manufacturers out there, I run Eaz-Lift Elite distribution with 1,000 lbs round bars and Eaz-Lift friction sway. Works great, but I don't ream on the system to transfer a lot of weight as my older Treg has (steel) a very firm suspension that has little sag with 800 LBS on the hitch.
Your receiver will never "rip off" or "break off" the back. This has not happened to one Touareg owner that we have read of (we would know if it did). There are eight bolts with a very high strength that hold the hitch to the box frame that runs between unibody layers from front bumper to rear hitch. This steel is high strength and is designed for loads WELL over the ratings we know of (it pulled a jet for example and lived). What could happen is legal issues if it is proven that an accident was caused by overloading / unstable / blown tire for excess axel loading. Otherwise you need to just keep all axel max ratings in spec and you will be fine running 770 LBS...this is my opinion only.
Do not moving things around to "make a heavy tongue work." It is unsafe and not fun (because it will be unstable and a pain to have things like batteries and propane not be where they should). Rather shop more and look into lighter trailers. I run a 32' (overall length) bunk house with a super slide and loaded weight of 7,500 lbs and 770 lbs on the tongue. The empty statistics for the trailer were 528 lbs on the tongue and 6,000 lbs dry and 7,500 GVWR (yes I am at the limit)...but we have it loaded pretty good which is how my tongue got so heavy versus the stock dry spec. However, because I purchased light with a light unloaded tongue, I have lots of capacity to carry cast iron cooking pots, real glasses, real plates, and so forth. When we camp we miss nothing
