There are a couple reasons I like the dynamic approach:
1. It covers more cases. Our robot could get involved in a pushing match and have the TCS still work (in theory)
2. It covers the case where the trailer starts filling up, and the ratio of the robot-trailer system's mass tilts more towards the trailer
3. It works as the field and wheels degrade and their CoFs increase or decrease
4. It works on the carpet.

The static approach will our fall-back if we can't get the dynamic setup working properly.
