Dually or no Dually

Hopefully this hasn’t been asked. Getting ready to sell my 2005 F-250 and buy a newer truck. I just bought a 28ft 5th wheel. I want a truck that will tow it very easy and that’s comfortable for long road trips. Not sure what manufacture yet ( Ford, Dodge, or Chevy) but I was thinking of getting a Dually. Any of you tow with a 5th with a Dually and without one? Just wondering if the Dually would tow the trailer much better. Money is not really an issue. Just want a truck that’s comfortable and tows really well.
