I must say mine has a timber floor in the tray (steel sides, headboard etc.) , however the timber is warped and there aint no polish getting on it! the only covering it has is a nice layer of red dust! (Ex Peanut ute form kingaroy) Only reason its timber is that it was on the car when we bought it, otherwise woulda been normal.....maybe i should just get a life like everyone else my age ........then again i could stay sane
