A bit of an idle suggestion here, but I recommend making the Truck's trunk size customisable from the Mods menu. I'm using a number of vehicle mods (including the Chopper) with 80-size Trunks which made the truck a bit superfluous, so I wanted to up its trunk size to 450 (the same as a small Storehouse from the Warehouse mod).
Initially I just dug into the Truck's definition file and changed the trunk size manually. However, I found that adding a menu option for this was fairly simple, so I edited one in myself :) I'm still using an older version of the mod since I'm on 1.0 and you may have done so already, but if not - letting players customise the truck trunk size would be nice.
