Most folks will say the 3.42 is fine for general use. I have a Cummins dually pulling 13.500 pounds with a 4.10 rear end. And I have to say I LOVE it. I can run all day with the cruise control on in 6th gear with no problems.
With that weight you could run 6th all day also. I towed 18-19k with my 11 HO Dually in 6th on flat to hilly terrain but at that weight I got slightly better mpg in 5th.
Op I would highly recommend a DRW with 3.42's with combined load to 28k. For a 5k plus camper the DRW with 3.42's would tow great and with the best mileage.
3.42's in 5th run same RPM's as 4.10's in 6th. I have owned both ratios.
