We pull a 2007 Kia 4 door on a Master Tow dolly with surge brakes behind our 3051.
The first time we used it I was such a worrier and thought I had made a mistake as I watched it steer itself on the back-up camera monitor...
We didn't have any trouble with it on our first 1000 mile trip and after loading and unloading a few times I finally got comfortable with it.
Another 2000 miles and I was laughing at myself for being such a worrier. We also learned in a hard braking situation that the whole rig will stop on a dime!
X2 on checking everything at each stop and carrying a spare strap set.
We also chose to put a pair of magnetic lights on the trunk as the ones on the tow dolly are low and next to the front wheels of the car plus TPMS sensors on the dolly and rear car wheels.
Our other choices were to buy a vehicle we could tow 4 down plus tow bar, braking and lighting or a car trailer.
This was by far our least expensive option.
The only negative I can see, if you want to call it that, is never get into a situation where you're required to back up unless you want to disconnect /reconnect everything!
