Single or Double Rear Wheels?
As stated in another post, we are considering going to a 5th wheel instead of a Class A. So I have another question. I know I’m going to need a 3500 series diesel truck to pull the 15,500 GVWR 5th...

The primary reason for a dually is the higher payload capacity. That weight of that trailer may have a pin weight that would require a dually.
Many claim you need a dually (DRW) for the stability or you will be "white knuckled" the whole time you are towing. But stability is not a problem with single rear wheels (SRW) as long as you are within the truck load rating.
Load range "E" tires inflated to 80 PSI, are rated to carry 3,640lbs each. So if the pin wieght of your rig, plus the wieght of the rear of your truck exceed 7,280lbs (3,640 X 2), you need to go with a dually. (3,640 X 4=)
Here is my wieght ticket
My single rear wheel 2500 HD has #5,760 on the rear axle, when the rig is loaded for travel, leaving #1,520 safety margin. Mine is what you described. 4X4 2500 HD Crew Cab, short bed. My rig is a 38' Forest River Work and Play Toy Hauler.
No white knuckles, very stable. I've hualed it thousands of miles. I do have Airlift 500 airbags, they help keep the rear end leveled out.
Before you buy a dually, start looking at ones driving down the road. You will seequite a few with the rear fenders banged up. Bank / fast food drive throughs can wreak havoc on a dually. I have repaired more than a few.
