I have a 20x8 dump trailer with a wavy and bent up floor. It had a plastic liner that started getting brittle and eventually cracked and tore out. I don't want to stick a whole bunch of money into this because I don't need such a big trailer on a daily basis, but when I need it it's great. It won't dump chips now without the liner so I need to do something. Just wondering what kind of cheap options I might want to consider in order to get it to dump chips again. Would plywooding the floor with a slick finish on it work?
