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.
^^^ This! The axle rating (axle manufacturer not vehicle manufacturer) is very high, the weight capacity is limited by the wheel/tire bolted to it, and the spring pack sitting on top of it. The difference between the SRW and DRW axle is the width... Think about all the people that go to 19.5" wheels for the higher weight capacity.
The longer wheelbase of the 8' bed will result in a slightly better ride in most conditions.
I owned a handful of duallys and a few SRW. For the trailer and use you describe, it would be a no-brainer DRW truck for you. Load how you want and not be on the edge of tire capacity.
