Towing vehicle(tow truck) With single speed transfer case

my only concern at this point would be If the rear differential and bearings are receiving proper lubrication.  I would think that it would not be an issue, but GM does some weird stuff in their engineering department. I have not had the chance to study if the lubrication system to those rear parts are independent, or pump driven. Maybe someone with further knowledge can advise us?

If the wheels are turning the internals are getting lubricated.  The ring gear picks up the fluid  as it spins the fluid goes where it needs to as long as the level is correct.

I just tow the truck on a dolly with the rear wheels down, transfer case and transmission in neutral and engine on. That way everything is lubricated just as if it was driving normally. Done 1,000s of miles now, no issues.

All fine and dandy except when this thread was started 4 years ago, the question pertained to the single speed transfer case.  The single speed case does not have a neutral position, therefore cannot be towed with any wheels on the ground.  It must be on a car trailer or flatbed tow truck (if it needs to be towed).  

 

Also, how you are towing is incorrect for these trucks, dolly with either the front or rear wheels on the ground.  

 

Caution: Do not tow this vehicle with two wheels on the ground, or vehicle damage could occur. This damage would not be covered by the vehicle warranty.

Dolly towing this vehicle is not allowed with either the front or the rear tires on the ground for two-wheel drive or four-wheel drive, regardless of transfer case.
