Airboat/Jeep Seats in Hammer?

I was wondering how to make enterable Airboat or Jeep seats in Hammer. Is there a downloadable pack that replicates the functions of the seats in Garrysmod? The prisoner pod is way too big for the stuff I would use it for. Alternatively, are there any entities that would simulate a seat? Thanks for the help

you could use the prisoner pod without a collision model, set to invisible. Then place a seat in the middle where you would be “sitting”

Check out this thread. I was trying to do the exact same thing and people were quick about answering it:
