paramsd: doesn't work on Ram HD trucks

### Describe the bug

I have been running a C3 on a Ram HD trucks since 10/2021. A large issue I have noticed is that the learner has a very hard time with these trucks. For example, the steering ratio is 15.61. However, I have seen the learner error from the liveParameters.steerRatio getting too high. As a test, I have raised the initial steer ratio to 25 and it errored once liveParameters.steerRatio crossed 50. Also, liveParameters.stiffnessFactor will continually learn down on a long trip. I have seen it get to 0.09 before if I disable the error. I am not positive about the exact cause of this. On several long turns, I have received the liveParameters.angleOffsetDeg error crossing over 10 as well. Attached is a log of the steering angle continuing to climb. The steering angle in the fork is set to 15.61.

### Which car does this affect?

Ram HD

### Provide a route where the issue occurs

### openpilot version

0.8.16

### Additional info

_No response_

Start with paramsd and the linked route log, focusing on the reported liveParameters.steerRatio, stiffnessFactor, and angleOffsetDeg values for Ram HD on openpilot 0.8.16. Done should be a confirmed cause and a verified correction for the reported learning and error behavior.
