This was the comment that has caused me concern since coming across it a couple of weeks ago.
Any ideas how accurate this is?

"For short distances it is probably OK.

Longer distances...?
Seems it would increase wear on the needle bearings that reside between the gears and the main shaft.
The gears on the mainshaft are engaged with the gears on the layshaft all the time. The gearset on the mainshaft are on needle bearings and freewheel all the time unless a gear is selected, then it is locked to the mainshaft.
When the engine is not running and the clutch is out, then obviously the input shaft to the transmission, and layshaft/mainshaft gearsets are stationary.
But if the car is rolling with the CV joints attached and the transmission in nuetral then the differential and outputshaft or mainshaft of the transmission are turning... and the the mainshaft will be spinning inside of the stationary gearset.
The gears being stationary will also not be splashing, swirling gearbox oil around inside the case to keep the needle bearings freshly lubricated.

This may not be much of an issue but for long distances I wouldn't do it.
Just have someone drive the car there or disconnect the CV joints from the transaxle while towing.

If you've ever taken apart a manual transmission then you know what I'm talking about."

I have helped take apart a transmission from. 911. But my roll as helper did not bring me complete understanding of the inner workings of the thing.

I would rather discuss this here and become more informed, than go ahead and start towing and find out the hard way.
I would rather resell all the gear that I've bought to rig for towing than cause big problems.
I'm located in northern AZ. Right now and see countless RVs. Rolling by towing cars all the time. It really makes me realize how much it would add to upcoming trips to be able to safely tow the 911 along.
