I have two trackers. A '95 Geo, manual trans 4x4 and a '03 Chevy, manual trans 4x4. I towed the '95 Geo on a dolly twice. It was a major pain. I first tried towing in neutral, with the transfer case also in neutral and the rear wheels on the ground. After a 200 mile trip there was oil all over the dolly. It came from the transfer case. After refilling and checking with a local mechanic I was told the tracker needed to be towed with the rear wheels on the dolly, transmission and transfer case in neutral, key in acc position and the steering wheel roped down. I tried that method for about 200 miles before giving up... I just couldn't get the front wheels locked down well enough to eliminate the vibration I felt, which I believe was from the front wheels.
I picked up a used tow bar from a local dealer and ordered a tow bracket online, received it in three days. Spent an afternoon installing the front bracket and haven't been happier. I sold the tow dolly for more then I paid for the tow bar and bracket.
If your going to keep the tracker as a toad, do yourself a favor and convert to 4 down towing.
