that sucks, and glad everyone is ok. but the statement, make sure the weight is all on the front of the trailer isn't right either. wranglers have such short wheel bases they don't make good tow vehicles for practically any trailer. the important part is the distribution, but if you have all the weight too far forward, your front end isn't on the ground hardly, and you will not be in control either.
and obviously there were no trailer brakes to help right this scenario either i assume. sounds like the trailer tried to pass you, if that was the case you were supposed to speed up actually.
