There is a baggage door support spring that I believe was original equipment on some Beechcraft baggage door. But don't try to buy it as a Beechcraft part, because it would be stupid-expensive. But You can find the same part sold generically. I think mine was something like $10.
It is a 'coil-locked' spring with nice brackets on each end. When you want to close the door, you poke the spring in the middle and it essentially folds in half and all its support effect goes away.
When you open the door the spring straightens out and holds the door open.
I'll try to find a vendor for it.
