I owned and used a dolly for 2 years to use for our civic which can't be towed 4 down.
Pros:
-It's pretty universal to a lot of vehicles
-nothing permanent to do to the towed vehicle.
Cons:
-In the rain it's nearly impossible to load a car
-in the snow it is impossible to load on a car
-straps are a pain
-takes much longer to hook, unhook
-storage
-another axle and wheels to maintain
-heavy to move around
-you have to find a spot for it at a CG - although ours fit under the rear of the mh, but I had to manually put it there since you can't back up. Fun if you have a hilly site or gravel.
In a nutshell a dolly is an option to tow a car when you don't have a car that can be towed 4 down. But it's a HUGE hassle. HUGE. Some on here will tell you it takes no longer and it's just as easy. And I call BS. I've done both.
We recently got rid of the civic for a CRV and 80% of the reason was to be able to tow 4 down. It is so much easier. Before it took me about 10-15 minutes to set up the dolly - this is contingent on how many times I have to line it up to center it on the dolly, put on the straps (dirty and cumbersome chore and super fun in the cold or rain). With my new setup it literally takes 3 minutes and that's only because I have to let the car idle that long. Hookup and disconnect takes about a minute. I don't have to line up perfectly because the arms articulate. Just 2 pins, chains and plug in the electric. I don't have to crawl on the ground and wrap my hands around the wheel to set up straps. Once I smashed the front of the civic on the dolly trying to load it in the snow and the car slid off the ramps and hit the front fascia. I could not wait to get rid of the dolly.
I am loving life 4 down. There is no comparison. I would strongly urge you to consider a vehicle that can be towed 4 down.
But like I said, a dolly is an option. But let's face it, if every car could be towed 4 down, dollys would cease to exist.
And no, not all front wheel drive cars can be towed on a dolly. Check the manual.
