<VV> towing a late model w/PG

[Landis, Art MR]

I imagine this is an old question but please indulge me since I'm a newbie.
I  have a tow dolly rented from U-haul.  It's the type that only lifts 2
wheels.  My question is probably obvious by now.  Which is better?  Towing
the powerglide equipped '66 sport sedan from the rear or from the front?
I'll be on the interstate for most of the 400 mile trip.
