That's hard on those dump trailers. I know from extensive personal experience. And for anyone who is going try and fill one with mud that's on the soupy side. #1: it won't lift more than 2/3rds full and A: have caution opening barn style doors. All that weight pushing downwards, isn't. Because of its liquidish state its also pushing outwards and those doors sent my 220 pound self reeling backward into the mud. If it would have clipped me in the head it would have knocked me out for sure.
