Tow flat or with dolly?

I have done both, flat tow and dolly tow. For me, flat towing is easier and quicker to hook up. However, I had to get rid of my flat tow vehicle and was left with a front wheel drive suv. To convert the fwd car to flat tow would have cost approximately $2600.00. That's for baseplate, trans lube pump, and braking system. I bought a Master Tow dolly with hydraulic surge brakes new for around $1800.00. It takes a bit more time and effort to hook up with the dolly, plus you now have the dolly to deal with at campgrounds. I try to get pull-thru sites to avoid unhooking the dolly, but that's not always possible.
