  • RAM auto-level rear air suspension system

    Iím in the market for a new RAM 3500 dually in preparation for going full time this year. Does the auto-level rear air suspension system provide any real value from a utility stand point, i.e. ride comfort, rear load leveling, etc.? I have looked at dealerís inventory online in a 6 or 7 state area and have not seen one truck equipped with the auto-level rear air suspension system. If it is really a good option to have I may have to order a truck rather than choose from existing dealer stock.

    Thanks
    Mike

      I have not towed with mine yet. So far the ride is improving as the springs and suspension settles in. I like that the truck does not sit AZZ high and when towing it will set level with a slight rake to the front and will maintain that stance all the way up to the rear axle rating. It calcs out to about 6K pin max.

      I can't comment on loaded ride yet but I am sure it will be good. On my 11 Dually I added air bags and changed to Bilstien shocks to help with some of the horrible roads. So by the time I added bags, tank, Compressor, air horns and in cab controls I was not too far away from the factory air price of $1,356.

          Thank you! I am glad you asked. I like to show off both as I think they are the best on the market. Hitch is a B&W RVK3600 and the toolbox is a HighwayProducts bed height 30" front to back. The toolbox came out of my 98 RAM it shoehorns perfectly between the D hooks down low and towards the front sides of the bed. If you order the box for the 15 RAM it will have about 2" of space on each side probably so you can hook to the D hooks. I like mine with the tight fit! Hitch is rated at 25K and 6,500b pin.

            Here is a pic of the truck in towing mode. This is the height it will maintain up to max rear axle load.

              That is the same hitch I have been looking at. I've been thinking of a tool box fuel tank combo but haven't decided yet. Will need a toolbox at a minimum. Looks like there is still room to install a bed cover if need be. Nice set up.

                Thanks!

                I lucked out on the toolbox. I found it on CL several years ago and used it in my 98 RAM then moved to the 11 now the 15. The box sells for over $1,000. Expensive but well worth it IMHO.

                If anyone decides to buy one of these boxes order it for a 94-02 RAM it shoehorns in nicely. The one for the newer RAM's will be about 2" smaller on each side so a person could use the "D" hooks on the front sides of the bed. I would never use the "D" hooks so I lucked out with mine fitting so good from the older RAM.

                  Here is a pic with the mew MS attached. With 100 gallons of fresh water on board here are the weights. It will look the same up to 9,750 rear axle rating.

                  Front 5,460 rear 9,580 = 15,040

                  Trailer axles 17,500 total weight 32,540#

                      You think a SemiTractor will stop a 100K plus load when the trailer brakes don't work?

                          Cummins,

                          Just now happened to notice in your pic that you have a tandem axle trailer. Those are 8,000 pound axles, are you actually running 17,500 pounds on axles with a total of 16,000 pound capacity?

                              Yes, Not too worried about it they are MorRyde and the tires are still under ratings.

                              This RV should have 3 axles but I am not worried a bit.
