If I understand correctly, when dealing with an ackermann drive robot (car-like), purepursuit algo for controller server works well with DUBIN algo in the smac planner. TEB works with both DUBIN and REEDS_SHEPP. Am I understanding this correctly?

In purepursuit controller params, I don't see any param that indicates backward velocity and hence it looks like REEDS_SHEPP won't work with it.

Indeed, there's even a ticket open to implement the reeds-shepp following in RPP https://github.com/ros-planning/navig.... It wouldn't be particularly hard to do, I just haven't had time to get to it yet. Might be something you could contribute if you need it!

I would like nothing more than to contribute to make the nav2 package richer. However, I am still new to Robotics, so it will take a few weeks before I am contributing.

Given RPP does not yet support Reeds-shepp, I am using TEB local planner. In your announcement about nav2 in october, you indicated that someone had tested the smac+reeds_shepp+teb_local_planner configuration. Is it possible to share these tested parameter config files (yaml)?
