flat towing or tow dolly

We had a dolly and had no issues with it. WE are now looking at having a car set up for flat towing. Two dealers gave us initial quotes for over $4000 to set up for flat towing. You can buy the parts for cheaper than what they are going to charge you. But you are still looking at $700 + depending on the dealer in just labor costs. So if you spend $400 for a baseplate, $500 for a tow bar, you are already closing in on $2000 and that's not including the cost of the braking system, depending on what you get. You can count on close to $1000 or so for that. It's not cheap to flat tow. You can tow with a dolly for nearly half the price. And it's not that bad. I won't hesitate to go back to a dolly. Although my wife is holding out. And the only reason is that she thinks its cooler or more elite to flat tow. But she will be cringing in another few years when she decides to trade in the car and pay another $400 for a new baseplate and other $350+ for the install of it...lol And not to include the lighting...unless you go with magnetic lights..
