The "diesel off-road package" RPO code B4U trucks must be kind of rare, I never found one near me when I bought my 2020 truck. Please continue to share your towing driving reviews and mpg results with the rest of us Duramax 3.0- 3.23 ratio folks.
Rubyralph started following 2019+ Silverado & Sierra - Routine Maintenance Quick Reference Guide, 2019/2020 Tow Mirror Installation, 2020 GMC Sierra 1500 3.0 Duramax (Aux fuel tank) and and 2 others
Checked already about this and found Titan makes Aux fuel tanks that fit in place of the spare tire for other pickup trucks. This would be an option once they make one for our trucks!?
Welcome, one of my reasons for buying my Silverado LT 3.0 Duramax was the tow rating at a reasonable RPM, I towed with a 2017 5.3 and was tired of the 6 speed transmission and the high RPM's at highway speeds. As for your question about the oil change cost between the Ram ecodiesel and the 3.0 Duramax this was another reason I picked the Duramax. I compared the oil, oil filter, and fuel filter cost and was disappointed of how expensive the Ram was for common maintenance! I did test drive a 2020 Ram ecodiesel and liked the engine and interior but did encounter a few harsh down shifts from second into first gear. The lower maintenance cost on the GM Duramax is what finally made me decide on the Silverado and the better mileage on the Silverado too. I get a discount at my Chevy dealership on parts and paid under $5.00/Qt. for 0W-20 Dextros D oil the engine takes 7 qts. vs. 10.? in the ecodiesel The oil filter was also under $5.00 (PF-66), I haven't bought a AC Delco fuel filter yet but I did look at the Ram fuel filter cost...WOW! Good luck on your new truck and buy what works for you!
3.0 Duramax LM2: Fuel Filter tools! T40 wrench to drain water from filter (located under the seat floor pan on the drivers side) 36mm 6pt socket to replace the fuel filter element.
That's excellent news!! My 2017 5.3 struggled to pull my empty aluminum extra tall enclosed trailer with the six speed transmission, that's one of the reasons I traded it in on my new 2020 3.0 Duramax! I can't wait to tow after the engine break in, I really like the way this new truck accelerates and shifts.

Can you please take a picture to show where the yellow wire is located? I want my led foot well lights to stay on while driving at night and when I open the doors, this sounds like this would do the trick?! Thanks Ralph
I test drove a new 2020 Duramax 1500 crew cab short box last month and really liked the way the engine power curve and transmission shifted in concert. IMO, currently this is the best engine and transmission combo offered in the 1500 GM trucks, worlds better performance than I expected and the truck feels nimble in town. When they supply crew cabs/standard box to the dealers I will look to trade my 2017 in. I do plan on towing up to 6K lbs., I also enjoy this truck empty cruising at 1500 RPM its a nice truck! I've owned many GM trucks and my biggest problem with the last two 2014 & 2017 1500 trucks has been the 6 speed transmission mapping and the throttle lag, I don't enjoy driving unless I'm on the highway not towing heavy loads. The last Chevy diesel I owned was a 1983 C2500 6.2 Detroit diesel what a change!
