Hi Michael,
The catch is if the motor will operate at such low voltages (well enough t pull the dolly). I am finding the motors need a minimum voltage, for the 2 RPM motor the lowest voltage I can operate it at is about 5v, which results in a speed of one rotation in 43 seconds, so slower than 2 RPM. The jaycar motor was the same, I found I had to have thevoltage higher than 2v, I didn't measure it but probbly about the same 5v too.

Would it be possible to reduce the supply voltage to your motor to slow it down a little?
edit> microwave oven carousel motors are good for hi-torque low rpm applications (2.5rpm (iirc)) but of course being 240 volt, they introduce a bunch of other problems.
