Drive all three trucks or at least your favorite two and chose the one you like best. I drove one brand for 10 years and never expected to switch to another. I did simply because I liked the way it drove better. This is the first time my DW actually likes riding in the truck. All three will (in DRW configuration) do the job with most all production 5th wheels on the road. Duals will make the ride feel more stable but may not be required depending on the pin weight and GVWR of the trailer.
There are many brand loyal members that will tell you x will explode on y unless you buy z. They can all have problems and many will have few if any. Luck of the draw on that one. We all have or have heard stories of issues with brand x. Buy what you like best, you are going to be "stuck" with it for a many years unless you want to take a bath.
