So I decided to get back into mod making, and for my amusement, will begin loading unlabeled images of my progress to tease the stuff out of you while rampant speculation abounds. ENJOY.

Alright, the main bit's pretty much done here.
Now I want to ask a few questions:
1. How do I go about mounting turrets on my turrets (As in, one locked to the z axis while another is locked to the y axis and the last is locked to the x axis.) Essentially a tank turret with mount gimbals with guns/rocket pods/etc.
2. How do I make it so that while the driver is located in one part of the vehicle, driving with WASD, the mouse-look is aiming the aformentioned turretonturretonturret action and firing accordingly?
3. can I make it so that a vehicle picks up its own separate equipment into it's own separate inventory? Like a gun-pod setup and a rocket-pod setup that can be switched between like items in a players inventory, and how do i make it behave differently depending upon what playertype it gets picked up by? Say, when a regular player picks it up and equips it, they get a massive crate that slows them down and they can't use, but the vehicle gets a mounted gauss cannon.
