Never mind, I figured it out already. But, in case anybody else wants to know.

//Open Hatch
this animate ["ani_hatch1", 1]; This animate ["ani_hatch2",1];

//Close Hatch
this animate ["ani_hatch1", 0]; This animate ["ani_hatch2",0];

//Open Rear
this animate ["ani_ramp", 1];

//Level Rear
this animate["ani_ramp",0.4];

//Close Rear
this animate["ani_ramp",0];
