    Parasitic drain

    Batram, I had an erratic 3 to 4 amp draw and erratic dead dual batteries in my 2020 RAM 3500 from the first months I owned it. I wasted a number of trips to 5 dealers trying to get the erratic draws identified. It turned out to be the batteries themselves! Stellantis assigned a Star...

    Time to replace my 2018 PW battery? Suggestions

    I will add another perspective: Back in the old days before all these computer systems that will erratically turn on and off and can drain batteries: My factory battery in my 2001 F350 (gas V10) lasted 12 years and 65,000 miles. Climate=Denver CO. However, on my other vehicles subject to...

    Time to replace my 2018 PW battery? Suggestions

    After installing 2 new AGM 80 amp-hr Walmart Everstarts in March of 23 I finally have a reliably starting vehicle and I'm starting to trust my truck. I paid around $170 each. I can't promise they are superior to other brands folks are recommending, but I have zero complaints after 9 months...

    Largest tires?

    You might also look at the Gallery at custom offsets. There may be some folks who have uploaded images and rub reports for various tires and backspacing combinations for your exact truck. https://www.customwheeloffset.com/wheel-offset-gallery

    Toyo AT3 vs Falken Wildpeak AT3W

    I also love the Wildpeak AT3s. I concur with ISellRams22 that they do tend to grab small gravel (my trailer is parked atop a 5/8- gravel bed, and the tires come out "studded"). With fender flares, and tires tucked up under the truck on stock rims, I don't care, and for me, the gravel sheds...

    Whats' the Difference in Fuel Economy Between a Cummins 6.7L H.O. and Standard Output?

    Goose, perhaps calling it a "dealer tune" could be a bit confusing to some readers. I was mostly trying to clarify that I have not yet upgraded to a custom tune designed to add horsepower. (Although I am still considering it to reduce some of the pedal lag, etc) I wrote a bit about the issue...

    Whats' the Difference in Fuel Economy Between a Cummins 6.7L H.O. and Standard Output?

    I've got 35k on my 2020 HO. Even towing my 15k lb trailer 14 ft tall up I70 from Utah to Grand Lake at the speed limit I will average more than 12 mpg. Did about 14 mpg hauling to Yuma and back to Moab. Without a trailer on the highway, typically 80mph in UT and 75 in CO, I will average...

    Switch next to lights

    That switch looks exactly like those included with some aftermarket heated seat covers. That would be my guess if we are starting a trivia challenge!

    No Fuel Cap

    Although these aluminum caps were labeled for 2013-2017 - it fit perfectly on my 2020. $7 and has a magnet to hold it to the filler door while fueling so I don't leave it on the bed rail or pump. The o ring holds it securely in place, but easy to remove. The link is no longer valid, so I...

    Battery dying sitting in the driveway

    Another vote for the battery as a likely culprit, but a rant about it possibly not being worth your time to go to the dealer. I took delivery of my RAM in December of 2020. Dual batteries. If the truck sat for more than a few days, both batteries were so dead that no FOB would be detected...

    Wheel Well Liners

    I installed the Rough Country 4609 rear liners in my 2020 Ram 3500 Tradesman. They were advertised for 2009-2018, but fit fine. I also installed some Bushwacker fender flares 50931-02. The combination made it a bit tough since it took a bit of leverage to get all the holes to align. But...

    Repeated dead (dual) batteries, 2020 Ram 3500 diesel

    I owe the forum an update and solution. I finally found a RAM dealer who determined there was indeed a faulty battery. It required that I leave the truck for more than a week and pay for a rental vehicle during that time (no loaners available). After all of that, it was determined that one...

    Adjust Default Volume settings

    Wirekat, I have been to three RAM dealers since I've had the truck. None have been able to fix the stupid problem. If you have any luck, let me know what to try!

    Avoid Cooper Tires Especially Discoverer at3

    I may be able to shed some light on the contradicting positive/negative statements about Transforce tires. My truck had OEM tires installed with different date codes. The two tires with the 0620 date code are terrible. The tire with an 0720 date code is performing okay. (The sidewall is...

    Why the decrease in HD tire pressures?

    OP, my experience with the Transforce tires has been terrible. I am now running them at maximum pressure (80 psi) per Firestone's suggestion in an attempt to counteract the rapidly wearing outside edge (the tread immediately above the whitewall side). Ride quality suffers a bit, but as you...

    Transforce Tire Recall

    I recognize it is a 6 month dated thread. But thought I'd add some info to help others. I have the same tire and size subject to the recall, but NOT the dates. Transforce ATs were the "upgraded snowplow package" OEM tires for my RAM. I've never used them as such; it has solely been a highway...

    Repeated dead (dual) batteries, 2020 Ram 3500 diesel

    2020 Ram 3500 Tradesman, 6.7 HO diesel dual batteries, dual alternator 440-amp, Uconnect 3, 5". No electrical modifications from factory. On at least 10 occasions my batteries have been dead during first 14 months of ownership (purchased new Dec 2020). Seems very erratic, sometimes dying...

    Adjust Default Volume settings

    My 2020 3500 Uconnect3 (5" display) has a similar problem that is potentially related. I've heard others complain about my identical symptoms. It is the factory unit with no modifications. Regardless of what source I was using (typically a Droid phone via bluetooth or USB cable), the radio...
