towing opinions on car dolly

I don't know about issues, but a few tips...
- you cannot back up that rig
- is your Duster a manual or auto? The best option to avoid transmission problems is to pull the driveshaft and plug the end of the tranny to avoid loss of fluid.
- You need to figure out some way to get brake/signal lights in the back of the Duster for the trip. The signal lights may not be so critical, but I think the brake lights would be necessary.
- plan your stops, nothing behind you has any brakes that will help you stop.

If it were me, I would consider driving the Duster. How many hours would that trip be for you? Leave early in the day and drive part way; stop at a park or other interesting place/FABO member to spend 3 or 4 hours and leave so that you get to the destination just before dark. You've done all or most of the trip in daylight, during the cool of the day, made a pitstop and didn't have to worry about driveshafts, towing, etc. JMHO.
