I take a lot of plastic off when I can but I don't fret over it much. My yard takes appliances so I have no problem throwing the plastic trim etc that comes off during break down back in the carcass. I don't cheat and stuff them with plastic I have lying around, just the stuff that came with the unit. My loads are probably 90%+ steel is I don't worry and the scale man doesn't bat an eye at my loads anymore. He can tell who the scammers are.
