ABS is pretty bad when it comes to UV exposure... Unless stabilizers are added... then, how good are the stabilizers used?
UV exposure makes it more brittle (I know a member here has a citicar - ask him about that
). Given the vibration/forces a trailer side skirt would see - it's likely to fracture if it becomes too brittle.
Honestly, sheet metal with folded edges (for a bit more stiffness) would be very appropriate here. Sure, it will weigh more, but longevity is key for an application like this. And besides, it doesn't have to be plate steel
