Device (other than airbags) to help rear suspension

However, over some of the larger bumps it feels like I may be bottoming out the rear suspension. I can't be sure if I'm actually hitting the stops, or if I'm only getting close.

Put a wad of chewing gum on the bump stop. At the end of the day a quick look will let you know if you've been bottoming out.

I suppose a piece of foam tape would tell you the same thing, but it lacks imagination. :)
