I used to tow my Subaru Outback 4 down. Now I bought a front wheel drive vehicle and switched to a dolly. I don't see much difference in hooking it up between the two. The dolly allows for far more versatility and is easier on the towed vehicle. My dolly has surge brakes and steerable wheels. I can use it behind any vehicle, and I can haul any vehicle with it (my son loves it, because he makes some money as a shade tree mechanic and uses it a lot for stranded customer vehicles)
I almost feel it is easier to hook up than the four down. That was relatively much work, connecting the car to the motorhome, installing the brake buddy inside the vehicle and making sure everything was connected properly (including a 12 Volt line form the tow vehicle to the towed one to keep the battery alive).
With the dolly I just hook it onto the motorhome, connect the brake lights and secure the car to the dolly. Not much that can be forgotten to be connected. And I feel it is a lot easier on the towed vehicle which does not need any alterations!
