They suck. I mean, they really, really, really suck. I know that's gonna make the owners of them in here mad as a wet hen but I'm telling you...... They suck. (ETA: When they're not loaded) Just my totally worthless opinion.
Look at the specs on virtualy every car ever made. Know what they have in common?
The Front Track is almost always wider than the rear track.
There's a reason for that. A big reason. Handling.
Then there's the parking. And the tires.
Some people love driving a dually. But, some people go swimming in frozen lakes, too.
If you NEED a dually, get one. Nothing else will do the trick.
If you don't NEED one, you've got my 2 cents.
Which is about what it's worth.
Good luck and do what's best for you. Don't listen to me.
Ask a couple of Dually owners how much fun they are in the snow
