    RDS Auxiliary Fuel tank/Tool box

    That is the engineering sexy! I want one now, its low enough to clear any 5th wheel with my 8 foot bed. Great find!

    DEF usage ?

    I thought my usage was way too much at first at 3300 miles I had used nearly 15 gallons! However I found the formula below on the Cummins site and the RAM site. Depending on load you will use 1-3%, more in extreme towing. I tow a 5th wheel up mountains so I went with 3% The formula is this...

    Brake Controller

    I live in the west valley. I-8 to 85 north to I-10. No way I was doing Phoenix rush hour on the Friday before Christmas in a new rig while sick. I may be a crazy a-hole, but I am not stupid. -Dave

    Brake Controller

    The tech hooked it up to a test jig at the shop. I have not measured the voltage myself. I got in with the rig Friday and was hit by Ebola-bird-SARS. I have been hold up inside all weekend. Only 'emergency' test I did was to slam on the brakes at 20 MPH in the parking lot at LaMesa RV to...

    Brake Controller

    It's not a score, that limits the discussion. I have a 2015 late year model, it has 2016 parts mixed in. There could be a range of trucks with the issue. Mine does not currently have the issue. So a late 2015 HD 3500 DRW with tow package, Cummins engine, and Aisin transmission does not have...

    Brake Controller

    The 7 pin was installed in the bed by the same shop that installed the Reese 5th wheel hitch. It did not come from the factory with either the hitch or the 7 pin connection in the bed. It is plugged directly into the stock harness and uses the stock controller. It works well. Your...

    Brake Controller

    No stopping issues. I may be mistaken by the wiring manufacturer I will check the invoice. I had a Reese 22.5k hitch installed and a seven pin installed in the bed. Everything a direct bolt in and no splicing. A side note my 2015 had a 2016 bed according to the tech. He had to re-order...

    Cummins diesel + Aisin transmission heavy hauling MPG

    Well I towed our new Dutchmen 3970 toy hauler from Tucson to Western Arizona. It's just shy of 17k pounds unloaded. Only 1200 miles on the truck so the engine still needs to wear in and loosen up. 10.2 MPG. Amazing how good driving trumps emission deletes. -Dave

    How Long are you planning on Keeping your Ram?

    20 years or 400K miles. Its the engine to tow my house full time so will be maintained like a home.

    Odd Rattle

    When my wife is not in the passenger seat, the whole seat back rattles due to the stiff suspension on my 3500. Drives me nuts but I can't figure out how to stop it. The rattle is due to the seat back bouncing when the suspension hits a jiggly bit.

    Service Trailer Brake System Warning

    Sounds like circuit latency. A passive way to check a sensor system is to send power to the circuit and then wait for the circuit to respond. In the old days that was simple as everything was controlled with relays in the Body Control Unit. Now days the ECU sits on tope of other system...

    Cummins diesel + Aisin transmission heavy hauling MPG

    The Cummins and transmission needs 6-8000 miles to wear in correctly, you may get 1-2 MPG as you put miles on it.

    Difference between "Normal" and "Tow and Haul"

    I can tell you from my butt-dyno testing that the Aisin tow/haul is EPIC. Without a load I can accelerate to 50 mph, let off the gas, and it downshift aggressively and uses engine brake. Enough to send you into your belts. Turn T/H off and it just coasts gently down the road.

    Brake Controller

    Any further update? I have a few observations. The sine BossHog posted is clearly an ABS signal with space left at the top for Active Yawn control. Does this sine change at all with Tow/Haul mode enabled/disabled? With T/H enabled the transmission takes over much of the braking and AYC...

    Cummins diesel + Aisin transmission heavy hauling MPG

    I am hoping for 11 or better. We will have to see. I took the extra weight of the Aisin so I am already behind the curve.

    20K toy hauler towing

    As stated, the OP has made up his mind, but anyone else doing research IGNORE the 'less is more' advice. I just bought a Voltage 3970 with a dry weight of 16242. Wife and I work from home and the garage is for the office. GVW for the RV loaded is 20000. I bought a HD 3500 DRW Longhorn. It...

    8.4n Looses its freaking mind!!!!

    As suggested, factory reset everything. I that doesn't do it, then its a trip to the dealer. This is why I paid for the electronics 5 year warranty. Most units will fail in the first 3 years or last "forever".

    Cummins diesel + Aisin transmission heavy hauling MPG

    Hello, New Ram owner here just bought a brand new 2015 Ram 3500 Dually to tow a 20K pound 5th wheel. Once I am past the 5-8K mile breakin, what kind of mileage can I expect at 55-65 MPH? I know air resistance increases fuel consumption exponentially, so anything over 60 MPH is eating up...

    TPMS system, can you integrate trailer tires?

    Hello, New Ram owner here. I bought a 3500 Longhorn which has TPMS system integrated for the truck's tires. I will be towing a 20K 5th wheel many months out of the year. I need to have a TPMS for the 6 trailer tires and I really do not want to clutter up the dash with a 3rd party sensor...
