I was fooling around, testing the shit-then (50 cal.) by attaching it to the truck. 

THATS when I got a light bulb in my head :D  I said to myself, " I wonder if you can attach objects into this truck , like a portable mini HQ or something"  

Guess what... IT WORKS!!!  
I was just fooling around with the ATTACH command in the editor. I can attach almost anything into the truck. Once attached, the Geom. Entity becomes part of the truck! What an amazing possibility! In this video I was just Testing if some of the Geom. entity works. You can say this truck is a alpha version of a mobile truck.

-What if you can do  a portable spawn bunker? or truck?...possible?
-what if you can do a portable energy site or HQ?? is it possible?
I haven't tried it yet but I can think of creating a Mobile home with this idea! Skype (Account name): iam_master_rambo
