We got a few guys that bang it together and go, never even checking a light, we have these swing door pups from Cali I think, the pin is set farther back and we have had several tip over at the warehouse, this one guy has a truck that the 5th wheel can be tricky to lock, he has had it since new, everyone knows of its problems, nothing major, ya just have to back into the pin and pull up a fraction and then back up again and it locks, I watched him fiddle with it for a minute then he gets out hooks the lines and cranks it up, puts it in gear and mashes on it, trailer came off right beside me! That thing hit the nose and the rear wheels came off the ground and it sat and rocked back and forth a couple of times, I was parked right beside it, all that could have been prevented by getting under the truck with a flashlight, some guys never learn, I have preached it to them, mgmt has preached it, still yet that 3 seconds turned in to a half hour of cranking a loaded trailer up, 3 seconds to bend over and look at the jaws, the next day he did the same thing, never looked, this time things latched properly.
Some guys just refuse to take that extra step, I will never understand why!
