Sounds like a good way to go....although I don't think I can tow my 05 Trailblazer (2 wheel drive) four down without an expensive modification to it. Using a tow dolly and towing it backwards sounds like a PIA.
I have an 2002 Ford Explorer that we want to tow on a dolly. 2 wheel drive. Ok to do this? Just put it in neutral and pray?
Best to find a copy of the owner's manual for your vehicle and see what it says about flat-towing. Most manuals are available on-line if you don't already have one.
Trailer Life magazine publishes a towing guide annually, as does FMCA - usually in the Jan/Feb/Mar issue.
Towing backwards on a tow dolly is not recommended for safety reasons.
Do your homework before you end up with an expensive repair.
FWIW & HTH. . .
