dieseldave:
we can do much much better than pics.Here’s a rather good
Manufacturer’s video, with sound.
I hope this helps.
oh dear, I just watched that whole video 
Anyways, being a newbie, I noticed that they said to “lower the legs until they touch, and then raise until there is a air gap at the skid plate”, When taught by my instructor they said to lower until it touches, and then wind back up a little, so you should actually drop the trailer a little bit. Which is the correct way ?

As far as I can see they are the same thing - is it me 
Both will let the trailer ‘FLOAT’ on couple up - won’t they
I have got a MAN-COLD so maybe it is affecting my brain - again 
maybe I’m just missing something obvious because I’m a newbie 
When I learned to couple/uncouple was told to lower the legs until they touched ground, and then wind them back 1turn or so, so the trailer is still resting on the 5th wheel plate. Then as you drive forward slowly the trailer drops to the ground.
In that video they say to lower the legs, and just before they touch, change to lower gear and keep winding until you can see a gap at the 5th wheel, so the legs have taken the weight and lifted the trailer off the unit. So when you drive forward the trailers not going to move at all, because its already higher than the unit.
■■? Maybe I should just giveup this trucking game
With air suspension I wind them to the floor and then a couple of turns more,
unless it is nose heavy, and I will raise the suspension to the max and wind the legs to the floor. occasionally I will lower the trailer airbags before doing this. We are fortunate in that several of our trucks are the same 
In the days of leaf springs I was taught to leave the legs an inch or more off the floor and drive out slowly. It helped the next man to compress his springs in cold weather without snapping them like carrots.

AH - that may be if you are going to use the air suspension lift on the unit to couple up.
Your instructor showed you the correct way if not using the above.
Thankyou Wheel Nut and ROG
