How do you equip a floating carrier in order to put stuff on top of it. I have one in my inventory and the game is suggesting I jump onto it to surf down a hill. I am holding the right button on the D pad and I see the carrier here. If i select it, nothing happens. I just keep whatever i had equipped before this.
Carriers aren’t equipped this way. You will need to open the cargo menu and select the carrier as if it were a regular piece of cargo. Either offload it or put it in your hand and drop it somewhere specific. Once it is on the ground, you will be able to interact with it as if it were a regular vehicle.
