Dolly towing is one big PIA. Fine if you are only making a trip south for a season. Horrible if you are doing a lot of traveling. If a CG does not have a pull through you have to unload the toad and then find somewhere to store the dolly. In the morning you have to do tis in reverse. Over the years I cannot count the number of times I have seen a rig on the side of the road with the toad gone but the dolly jacked up and the hub and wheel missing. The owner has had bearing troubles and taken the assembly to a repair shop!
