A Ram dually diesel with the Aisin trans and at least 3.73 gearing to make life easier for you truck. If you ever plan on a bigger or heavier RV then get the 4.10s. I'm not a fan of the factory air-ride as I prefer the leaf springs for reliability. One with factory 5th wheel prep would be nice too along with the B&W 3600 to go with the factory puck system.
Since you have the 4.10's you already know how well they tow at 1,750 rpm in 6th at 60. 3.42's give the same rpm in 5th. This works well with the AISIN because of it's lower starting gears. I have driven my Sons 3500 SRW with 14K dump VERY overloaded with combined about 28K. He has the AISIN and on grades it took off very easily. I towed that weight with my 11 HO Dually and 68RFE, only issue was getting the load rolling on the grades. The 3.42/AISIN combo can't be beat for 28K and under. RAM says the same thing just link at the chart below, read the bottom three lines.
Please tell me of ANY reliability issues with the Factory Rear Air ride on the RAM 3500's???
I agree the puck system can't be beat along with the B&W
