Hey Guys, I made an amphibious AA-Truck with a full working interieur and a lot of functions. This Truck can do following things:

AG1 Start the underwater propeller
AG1 VTOL up: retract the Wheels
AG1 Trim up: move out the propeller

AG2 Activate All-Wheel-Turning

AG3 Turn on lights

AG4 Activate Night Vision in Cockpit(Gunner) view

AG5 Small but very accurate Minigun

AG6 SHOTGUN for near enemies

AG7 VTOL up: jack up the car

AG7 Trim up: open the doors

AG8 Deactivate steering and engine

Tips:

When you enter the Water, throttle to 0%, then deactivate AG8, and then activate AG1 and put poth levers up.
If you want to go on land, first put your wheels down, turn on AG8 and slightly move the prop up.

If you have any questions or something, ask me. If not,
Have fun!
