We went from a 4 down Jeep Wrangler to a FWD Jeep Renegade that must be dolly towed or towed 4 up. Towing 4 down was easy but costly, as the Jeep had to be modified to accept the tow brackets and add the wiring harness plus add in the costs of the tow bar itself plus supplemental braking. It really is about a wash as most tow dollies run about the same costs with either electric or surge brakes.
I do think towing 4 down is a convenience as it is simpler to connect and disconnect than putting a car or SUV on a tow dolly and strapping it down. Tow bars can be left on the RV tow hitch, no need to store them unless another hitch is required. As others have mentioned, a tow dolly can tow practically any FWD vehicle without modification.
Most tow dollies can be stored under the rear of the RV at a campground or in storage and some even store standing up on end (for garage storage, etc.)
