duel's will be a little more stable, Alot more stable if you have a 5th wheel trailer. But if you tow using regular trailer hitch. single wheel or dual are pretty close to the same. You should have a receiver hitch with sway bars. Then single or dual are the same. Or pretty close. I use a set of sway bars on the dually too, so it's good insurance having it. But basically. A 5th wheel trailer is where the single wheel and duals are different. Duels makes it alot more stable in the wind and such.
