If you let it idle for extended periods without EB engaged it will elevate the rpm's.

I never know if or when mine is doing a re gen.

when your RAM trucks go through regen, do you have the elevated idle, about 8-900 RPM's? extremely annoying in the GM's.


no


Yes if it needs to, mine does.

I have only rarely noticed an active regen in my truck. Once I heard a slightly odd sound (possibly a slightly elevated idle) while stopped at a red light. Like I said... only noticed that once. Other times I stop the truck and notice a slight burning smell, which I assume is from the heated exhaust during an active regen.

Other than that, never noticed anything... not even a noticeable blip in fuel mileage. I mostly use my truck for hauling though, so I think I usually get a passive regen.


This time of year is when mine does it the most. Camper is parked, boat has not been out of the garage and my DW drives it to work when we get snow/ice. A lot of idle and slow easy running. Don't notice it much during the towing season.

Yep, thats pretty much how mine is also but I have seen a couple MPG drop occasionally when driving that I associate with regin but that's the only evidence I've every noticed if that's even the cause. As for mileage, not to get in any argument here but I'd really be surprised if anyone even with 3.42 gears would get 20 mpg at 70 mph being the non aerodynamics of the front of the Rams, let alone getting that mpg with 4.10s. Not saying its impossible because nearly anything is possible but... The only way I get those mileage figures is when running 55 mph on a calm day, level road and I can push 21-22 mpg, but at 70, mine drops to around 16.5. I did do 25 mpg one day at 55 but I think I had a tail wind if that counts...Lol! All in all, I really like my setup with 4.10s, Aisin trans, B&W hitch and standard spring susp. Oh almost forgot, I have mpg getting bed cover too!

Even if I drove my Dually at 55 on a to and from trip no wind at 55 I would be luck to get 17, take it up to 70 same trip it will be 14 or so. I don't believe the bed cover makes a difference. But hey like I said before I gots a lemon as far as mileage is concerned. [emoticon]

Ricatic, good seeing you in here buddy. You can see my truck in my sig. My 5er is weighing in at 18,250# total GVWR is 28,400# now. Love the rear air assist. I’ve never gotten 20 mpg, but running empty, driving at 55-60 my have by 18 mpg.. but it’s rare. I e towed my 5er in the mountains of WV, VA, TN, NC and SC, ( several 7% grades on I77 and I64. Also from WVa to Cleveland TX... towing at speeds as high as 70 mph. Could tow faster, don’t feel the need to. Depending on terrain and speed, I’ve averaged as low as 7.5 and at times hit a little “right at” 10mpg. (Hand calc). Best I’ve ever gotten solo has been a little over 17 mpg, hand calc. For the first time, I will say, while towing on flatland, I don’t even know it’s back there, ( never really towed in flat land until heading to TX.
I hope you and your family are well and hope you’ll be happy with the Ram3500 dually. Love mine, dry comfortable and a towing machine

Jim

Jim good to see you here also! Curious at 28,400# combined are you over 14k on the 6 truck tires? I am guessing VERY close either way. NOT that it matters.

Actually, latest weight check with my wife, me, two dogs , full tank of DEF and full tank of diesel, loaded for trip, and 5er loaded for fulltiming, heading to TX in late Dec of 17 was 5600# for front axle, 400# under FAWR Of 6,000#
8200# for rear axle, 1550# under RAWR Of 9750#
=13,800# .... 200# under GVWR. 14,000#
=10880# under GCWR Of 39,100# .

You . Loaded truck without 5er
Steer axle=5500#
Drive axle=3940#

With 5er
Steer axle = 5600#
Drive axle= 8200#
Trailer axle= 14,420#

Pinweight 8200-3940# = 4260# + 100# on front axle=4360#
Trailer weight is 14,400# + 4360# = 18,760#.. camper rated at 19K with 2 8K axles. Camper is probably lighter now. Very recently got rid of the couch/ sleeper and 2 recliners. Replaced with better furniture but lighter.
Hope that helps
Weights are from Certfied Automated Truck scales at truck stop off I40 in Candler NC.

So we dropped out camper in Brunswick GA this morning and drove an additional 300 miles into Florida. Set the cruise on 75 mph and were mostly able to maintain that speed. Hit some traffic on I4 in Florida and slowed for a while, but eventually back up to speed until we hit 301. Went through some towns and into the city, finally getting to Anna Maria Island. Truck was loaded down with stuff, probably close to 9200 or so lbs total rolling down the road. Averaged 19.1 mpg hand calculated, over that 300 mile trip at 75 mph.

At lesser weights and shorter distances I have been able to get 21 at 75 mph on I-70 through Maryland.

I have always “been around”...just been so busy with work that posting was the victim of not enough time...glad you could jump in....I was hoping your expertise added to Cummins...and the others would ease the learning curve on switching to the Ram...

The mileage numbers that you and Cummins are posting are similar to what I was getting with the Chevy Duramax 2wd so I can certainly live with those figures...and enjoy the added power, comfort and weight capacity...our Cyclone was right at 19000 pounds when I weighed it loaded for our Oshkosh trip...

For those who want pics...I will start a new thread when I get the truck...right now it is 1100 miles away basking in the warm weather...stay tuned...Cumminis V was right about his “inside info” on the 4.10 gears...actually...my new truck is a virtual twin to his...2015 Ram Laramie with Aisin trans, air ride and automatic everything...heated and cooled everything...and it comes with a 24k Curt puck mount hitch...Being an avowed B&W fan, I will try the Curt but will likely go to B&W after the mad money fund replenishes...the sooner than expected replacement of the Chevy dented the budget a bit

Thanks again to all for the help

Regards
