Can I make the decoupler even less forceful than 1?

[LMksp]

I have a couple 1-kerbal ATVs that are only 0.3T each.  They're all loaded into a 2.5 Service Bay and dropped to the surface (Duna).  The best I can think of is to attach these vehicles to the floor of the service bay with the smallest (.6?) decoupler.  However, even with the force set to 1, the vehicle gets shot around the inside of the bay or sometimes even bounces out and lands in places that make it impossible to 'board' - down a cliff, under the ship, etc..  

- I'm completely "mod free", and would probably prefer to stay that way.  

- Clamp-o-Tron Jr docking ports are way too bulky and heavy for these tiny vehicles (so small that 4 fit in a 2.5 service bay!)

- I thought of strutting from the decoupler to these vehicles, but they have to be attached to do that - which defeats the purpose..

Is it finally time for me to give up and install KAS?

Are there any other ideas I can try first?

Can you post a picture of what you're dealing with?  I have a feeling that it's not the decoupler, but because some invisible clipping is going on, and that's what's ejecting the vehicle.

If the issue isn't clipping as @Geonovast suggested, then maybe you can use a junior docking port instead. I am pretty sure that they don't have a force.

Hmmm... yes, you're right.  This is a clipping issue.  In order to decouple, the Kerbal seems to have to get on the ATV.   That's when the top quarter of his helmet clips through the top of the Service Bay.  If I mount the ATV to the decoupler and the decoupler to a flat construction sheet - the decouple at a force of one is perfect.  

Thanks!
