Long distance dolly towing

What gear ratio?

Likely as long as your lube is Good and full you will be fine!
3.73's

check the local laws in the states you'll be going through. some are very specific as to what you need to dolly a car on their highways.

as long as ya hve gear oil in the rear i don't see how it could be a problem.
Hmm, hadn't thought of that on the laws. I will look in to it.
