Here is when I incorporate my most favorite piece of customizing equipment. A ladder from maruders. You can cut the thing up and use it for all kinds of things. Here I made a bracket to hold the ammo box for the big gun. In a pickup at high speeds it could fly around everywhere. So I cut the peg off the backpack of a 25th roadblock to use as the ammo case and then cut the ladder to fit, a little superglue and bam! instant bracket.
