The absolutely most important thing about owning a dump trailer is making sure the doors stay pinned open when dumping...... don’t ask how I know ! When dumping really heavy loads that are not completely centered side to side the bed will flex no matter the brand , and depending on the latching system can come unlatched ! Just a heads up . Also mine was supposed to lift /dump 15k , filled it with concrete from a demo job and just wouldn’t lift it . That blows also ! Probably one of the most handy things I own tho if you know it’s limmits . Oh one more thing , going to the gravel yard the guy running the loader isn’t always your friend , some are great and will give you exactly what you want (tons) some will over load the crap out of you !
