Side dump vs end dump safety questions

We tried a couple of side dumps for doing levee repair work. For that narrow use they did fine. Everything else we tried them on we wound up going to a bottom dump or an end dump.
We do a lot of spreading and a lot of stockpiling. The side dump just doesn't do a good enough job. There might be a trick to spreading with one but all we got when we tried dumping while moving was busted frame bolts, twisted cross members, and trailers that sat most of the time. Stockpiling with a side dump might be alright if you're pushing up your own piles but eventually the guy on the loader will get tired of having to push every load you bring in. If you're feeding a plant and dropping into a short grizzley you better bring a broom.
Every end dump I've seen turned over was clearly pilot error. Sometimes the driver let himself get lured into a bad dump spot but it was still the driver's choice. We were on a levee break job where the job foreman wanted three end dumps dumping side by side on fresh uncompacted fill. At night. We told him no. So did the next three. And the next three after that. Sometimes you just have to take a stand.
Homeowners are the worst. You can talk to contractors, eventually you'll find a common ground. Homeowners are just needlessly stubborn about what they want. We'll sub out every homeowner job that comes in. The loss in revenue is better than the aggravation of getting your truck and trailer pulled out of somebody's sewer or leach field.
