Here is my answer to Chuck from the same PM questions.
Personally I would contact DaveSmith in Idaho along with Dennis Dillon. They are a good place to buy or at least see where a local dealer should be for price. The general rule off the lot or ordering is invoice minus any incentives at the time. For a truck like mine LongHorn fully loaded you should get around 12K off sticker, maybe more,
You have to have a dually! Towing capacity is not the issue it's what weight can the rear axle handle. My RAM Dually can carry 6K the SRW 3500 is no where near that. Your RV loaded will be at least 17K so 25 percent of that for pin is 4,300#. That is way over SRW territory. Besides a SRW will not be able to handle the rV in a panic situation like a dually can.
As far as the details on the truck yes a B&W RVK3600 is the best hitch hands down out there. I personally like the LongHorn for it's VERY nice interior with top quality leather seats that don't leave you sore at the end of the day.
The AISIN is for sure the way to go with the extra power and lower starting gears that make getting the load rolling with ease. For your weight the 3.42 gears will give you the best solo mileage but they will perform as well as the 4.10's towing in 5th 1,750 RPM's at 60 the same as 4.10's in 6th at 60. If you ever plan on a heavier DRV then I would highly suggest forgetting the 3.73 and go to the 4.10.
The factory rear air ride is a great option. The unloaded ride is better than the trucks without the option and the loaded ride is great. The system keeps the truck at the same ride height automatically.
Rear air came out in 15 but I would buy new as the used prices are not too far from new.
If you want the icing add a HighwayProducts bed height 30" front to back tool box. They are NOT cheap but very nice!!!
