    Hey all! A little background, I’ve been driving tandem dumps for 5 years, mostly interstate snow plows but recently doing aggregate delivery for a local landscape company. I’ve recently acquired my Class A and started training in an end dump rig (frameless rock tub) and learning how not to become yet another green driver to roll their trailer as we’ve had several here do just that. I’ve been looking into changing companies due to poor management and rumors of impending sale/shutdown of my current employer and I’m weighing my options.

    In terms of safety, what separates an end dump from a side dump? I know you can roll both if you’re not careful but in my mind a side dump rig would be less prone to roll over. Am I wrong? To those of you with experience with both, what do you prefer and why? Thanks and happy Friday!

    One is actively trying to flip you over and the other one just does it on a whim. If you own the vehicle, consider what a side dump constantly twisting does to the frame.

    I would take a frameless dump over anything else any day of the week, most of the problems stem from drivers not putting them all the way up in the air and trying to move them with weight too far up the drafting arms instead of on the tires where it belongs

    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.

    I’ve done both, side and end, pulled double sides, never had an issue, but must pay attention! Same with ends, not a fan of frameless, their lighter, but I prefer a 1/4 frame, keeps the backend up off the ground, better for paving (IMO) plus their more stable
     
    Dino soar Thanks this.

    I’d like to add a question. Do the man doors on end dumps make it so you don’t have to climb up the side or do they serve a different purpose? I’ve seen both on trailers and was curious.

    Yes. Much safer and easier to enter from the catwalk than over the side. Especially climbing out.

    Depending on tarp set up, most man doors make it more awkward to get in then just climbing over imo

    Thanks for the insight, everyone! I’m still running an end dump but an opportunity to switch to a side dump has presented itself, now I feel much more informed to make a good decision.
