Do I really need a Dually?

Something I have not seen mentioned in this thread (maybe I missed it) is that a DRW truck will have significantly improved roll stiffness than a SRW. 19.5 inch wheels, airbags, antisway bars etc. cannot change this fact - it is simply physics: the rear track is about 25% wider.

Wrong - the mounting point (pivot point) for frame to axle is the same for the SRW & DRW.

Now as far as resistance to side wind, etc., the DRW will fair better than the SRW. The SRW will "squirm" more with strong side winds. I have driven both SRW & DRW with identical Lance 1030 campers. Very little difference.

Well, to be pedantic about it: the roll center is the same, the suspension roll stiffness may be the same, but the weight transfer and tire roll stiffness is different by the track difference.

Yes, there is a difference. But even more than all that, the level of competence and experience of the driver plays a part.

Most people that have never owned and or carried heavy loads in pickup trucks would be much more comfortable owning a DRW with a TC.

I have 50 years experience driving overloaded pickups. We routinely loaded 60 bushels of peaches on our LWB 1/2 ton Dodge pickups back in the 60s. With proper tires and overload springs, I was never uncomfortable driving those trucks to market.

I did have an uncle with a 3/4 ton Ford loaded the same and I had a blowout on the left rear driving 60 mph. I was never out of control and pulled to the side of the Interstate and changed the tire.

By the time I was 16 years old, I had thousands of miles of seat time driving loaded trucks.
