I can only agree with Eddie Snax’s method, whilst i was in your camp in the days of steelies CF, even i have moved with the times
and make use of the air suspension to allow a much more gentle pick up…which helps keep everything nice and clean, and puts the grease where it should be.
Pick up ramps aren’t made like they were in the day of steel springs, they were solid jobbie made to run a loaded trailer up and down for years, if you did that with the thing we now have the bloody silly little bolts holding it on would sheer off.
That’s the issue I’m referring to.In that for want of a bit of regular greasing and washing you’ve created an inherent institutionalised flaw in the coupling process with foreseeable results.
In which case you’ve gone from a no option good practice situation of always reversing the jaws against the pin with the pin being at the correct height ‘before’ it’s coupled because the trailer is where it should be resting on the ramps and/or then the fifth wheel.Therefore no possibility of a mis couple or over shoot of the pin.
To a situation in which people are coupling up trailers starting from an inherently,intentionally,incorrect vertical misalignment between the unit and trailer.Which is then,hopefully,possibly more by luck than judgment,only sorted out by stopping the unit in time,within the relatively short distance,between the trailer being over the fifth wheel,but before the pin has entered the jaws,then raising the unit using the air suspension to correct the misalignment which you’ve intentionally started with. 
Which is bonkers just to save a bit of grease being shifted off the fifth wheel of which we were obviously never bothered about before so why now.As for the ramps issue there’s not much point in fitting ramps if they aren’t fit for purpose.While where they aren’t a factor for whatever reason that’s then what the chamfered forks on the back of the fifth wheel are for.In all cases the point being that best practice is to make sure that the trailer coupling surface is lower than the fifth wheel table height from the start of the coupling process and that applies whether it’s steel or air.
CF me old mate, back in the days of steelies you could nearly see the bloody king pin through the back window most tractor units had, so short was the kin pin length, it wasn’t till we started getting trailers with a 48" pin that the grease situation became a problem, you pick the trailer up your way and what doesn’t get smeared up the front of the trailer gets dumped all long the rubbing plate, by the time you’ve reached the king pin you’re down to bare metal in places.
No one’s deliberately trying to misalign a pick up, we endeavour to slide it under to just before the king pin, we might undernestimate it and still be 2ft short of the pin, but we don’t risk going so close that we might have missed it…in that respect those lazy sods who do it all on the mirrors, and many of our tractors bear the scars to prove, are going to cause damage sooner or later.
It only takes a bit of nous and care.
If the numpties doing the damage were paying for it, the damage rate would drop drastically (ironically if they did but know it they are paying for it with race to the bottom wages), as it is some of them wonder why they’re stuck on crap money working for crap companies who presumably assume the damage caused by employing crap is worth the cost saving over cherry picking those who actually give a fig.
