Is there a way to do this? Any help is appreciated.

As of the version on uMod, no, there is no way. Currently only storing option is "Store Vehicle On Plugin Unloaded / Server Restart". It also would not be storing the entities in/on the vehicle (at least to my knowledge) so its not super beneficial. That setting basically just doesn't kill it when it unloads the plugin (which also occurs during a restart).

Not quite sure what your goal would be either in terms of storing the vehicle, could you maybe expand upon that?

I am so sorry...after all this time I had no idea you responded. It's not really an issue on the surface, For example, having the CH47 able to purchase means I can count on 1/2 dozen or more parked in crazy places, all over the map at any given moment. If when the players log off they get "put away" that would be ideal. Not super critical.I did however notice that it is no longer refunding the horseshoes when I despawn the horse. Fuel still goes back in my inventory when I despawn the mini...just not the horseshoes when despawning the horse.Thank you!
