Before doing anything type this into the console: GolfCartVehicle.DefaultTire = MonsterJeepTire;
First, create two vehicle spawns. Spawn a horse; and a GolfCart. Name the Horse Vehicle spawn "stan". Then, name the Golf Cart spawn, "GolfCart" . Open your client-side console with the ~ button. Type the following commands into this console in this order:
_stan.vehicle.changedatablock(tankturretplayer);
_GolfCart.vehicle.mountObject(_stan.vehicle,4);
