Hooking and unhooking questions

What I suggest you do is practice by sitting up some cones the width of a normal trucking spot in a wide open parking spot. Practice there until you feel comfortable and then practice in the Werner yard. When you first start backing Get Out and LOOK often. If the trailer is not going where you want it in the begining, it is not going to get better as you keep backing. STOP and get the trailer started in the correct place before you get in too deep. Watch for tail swing, it is what gets most new drivers. Werner has great videos on the driver education portal. Watch them over and over, take notes, then go try it.

 

What would be the purpose? Why put extra stress on inflating the airbags -after- hooking to a full trailer?

 

I drop and hook 12 plus times a day,I get under the trl look to make sure king pin is lined up and slowly back up.Works for me everytime.Today I hooked up to a hide trl and it was a good 3 inches lower then the fifthwheel because the yard guys didn't lower the landing gear low enough.I never dump the bags while hooking up unless I have problems getting under it like today.But I do always dump the bags when unhooking.

 

I dump the air both hooking and unhooking.
