Papercraft Trailers for War of the Dead
These are little more than boxes, model-wise, but they've still got a place on the table - particularly since in my War of the Dead campaign, the player group "upgraded" to a full covered trailer in the hopes of avoiding a repeat of the various times they've had stuff spilling off the trailer, or stolen outright.
The larger one has the "Daring Entertainment" logo spraypainted over with some "graffiti" that, if one looks very carefully, might spell out the name of a certain glam-rock idol character.
The smaller one is meant to be a "generic" rental company brand, though suggesting the appearance of a certain other brand that's a common sight on the highways.
As with the humvees, I made bottom panels, though they're far less detailed (basically just a big dark panel with some support struts going across, bottoms of the tires, axles, and basic suspension, but there's no drive train or anything noteworthy like that, since it's just a trailer).
