How to get a character onto a vehicle

So players have the option to customize various cosmetics on a character as well as some stats but the character can get on / off a skateboard. When possessing our skateboard physics mover what would be the best way to feed in a reference of the player character (stats, cosmetics and all) into the mover? Right now I am feeding in a reference variable but that causes a few issues, mainly with the player popping onto the board and the camera flash jumping from the character on foot to being on the boards camera. I need a smoother system, just a point in the right direction would help here.
