Dump tri axle and pup trailer

Always dump trailer first and don't pinch hoses when jack knifing dump all air ride while while dumping

 

Untill you learn your equiptment get out and look while jacking the trailer around. Over jacking may bend the toung, break the pintle hitch or cut air, electric, and hydro lines. Try to jack the trailer to the drivers side unless its not possible and pay close attension to the blind side while doing so. One thing that will happen is the trailer will lean as is skirts the edge of the pile that came from the truck as you pull forward. Watch out for thing like trees, polls, or buildings that are close to the trailer as you pull away from the pile. I once dumped salt it a salt dome close to the door. Dumped the trailer first then jacked the trailer inside the dome and dumped the truck just inside the door. As I tried to pull out the trailer came up on the pile from the truck and wouldnt clear the door frame. Luckly I seen it before I hit the building but the only way out was to shovel the pile out of the way of the trailer to clear the door. 2 hours later I was out.

 

Worst case do you have to dump the trailer drop it. Dump the truck ,rehook and go. Does not sound like fun.
