What “engine failures” are you hearing/posting about I have had my ‘24 ram 2500 w/6.7 ctd six months only, and it tows beautifully and i’m having zero problems even when temps dropped to 15f. Bought left over 2024 ram 2500 In back of owners manual it talks about pulling a load to fit and finish drivetrain How much weight and how many miles should i do that. I have a new '22 ram with the 6.7 cummins with 13k miles on it
It has been in and out of the shop for the last few weeks for a check engine light The code refers to regen issues The mechanic says it is a regen issue and asked how i used the truck (like i needed to not use it too hard) 2020 winnebago horizon 42q 450 hp cummins isl 8.9l 11,000 miles driving home last weekend from a short trip i hit a very slight grade and noted that even floored i was losing speed So upgrade to 450/1250 hp/tq or is 380/1150 hp/tq good enough for those with the l9 380hp motor in their dp rv?? Discussion on the best and worst years for cummins isl 400 engines, including considerations for common rail fuel system and def system.
Started my annual summer trip from phoenix to denver pulling my 35 foot 5th wheel to denver, truck running like a charm.then upon arrival in denver, truck running rough, wont idle, no power in low end of throttle Then it started to go into regen every 150 miles, about 10 to 15. A number of oil for cummins 6.7 may be approved for the same cummins engine, but subject to shorter drain times Aftertreatment engines require oils with lower sulfated ash content.
