A few years ago, RAM derated trucks and my 2020 RAM 3500 HO w/4:10 rears was included. I bought it with the GVWR of 14,000 lbs. Max tow of 34,305lbs and GCWR of a whopping 43,000lbs. (PS: I'd NEVER tow that much as the brakes on ALL Dodge/RAM diesel have sucked since the first I owned in 1998)...
To be quite honest, my 2016 RAM 3500 HO with 900 Ft torque was way more then I ever needed for a 40+ RV at 18K. The only reason I sold it was pin weight. Maybe the 2025 will fit the bill etc?
Ever since the Y78 recall was completed in 2023, the exhaust brake does not slow the truck down while in cruise control. This applies to either Full exhaust or Auto Exhaust brake. I have been back to the dealer 4-6 times and reflashes done etc to no avail.
Prior to the Y78 recall, it would...
I don't have a aux switch below the e-brake switch. I did get a new download from the dealer this past Monday that may be the fix for the issue. Came out in May of 2023. I will find out next month when I go into the mountains camping with the 5th wheel. It was TSB 18-067-23.
Mine is good except for in "cruise control". Does not activate in either auto or full e-brake. Makes driving more "interactive" then before . Now I have to get it to do what it used to do automatically.
When exhaust brake is on FULL (yellow color dash light) and you let off throttle no activation or cannot hear it working? It should work at most speeds until below about 15 mph to help slow you down. Its even more aggressive in tow haul mode. Auto Exhaust brake is not as active as full and its...
It's awesome when it works right. Going down a 6% grade if the speed is 50 mph I set it at 45-6ish and the truck will fight like crazy to keep me from going over 50mph..Thats with a 17K 5th wheel. I'm sure heavier it might be a bit different. Now I have to throttle down the hill and tap the...
The last 4 I
They reprogrammed the PCM after the Y78 was done and I can only guess that's the cause. The ebrake etc has no idea what Injector pump is on the engine,. I believe it is controlled by the PCM telling it what and when to do what etc. Probably missed a line of code for cruise control...
Since 2012 when I bought a "Max Tow 3500" (This truck being #5 of since then) with the factory ebrake, I have used the cruise control in the mountains etc. If going down a 6% grade recommended speed 50 I would set cruise at 48mph and the truck would work hard via ebrake to keep me at 52-54 etc...
I am very happy to have had my injector pump replaced recently. However after the replacement, my exhaust brake does not function while cruise control is activated. (It is in Tow haul and tried it both in full exhaust brake and auto exhaust brake) Two others on this board are having issues with...
