Because I don't and have never had a air ride back end in a truck I didn't think bags up or down would make a lot of difference 

I guess it might rotate the axle housing and this reads different 

However if I think about a normal spring suspension the oil is checked at ride height as thats all it ever is

So to me even if it was airbag, common sense would tell me to check it at ride height as tgats were the axles are as you drive along

But I dunno with this fangled air bag stuff 

Apparently they enhance ride or comfort or some such thing, but really, aren't we kust taking away the good things in this whole experience ?

The air bags have nothing to do with it,check the bottom plug hot,after a run..

The air bags rotate the axle when filled. I had a guy do maintenance on the truck and he added oil while air bags were down.  I checked the oil 2 days later while it was still in the shop but I aired up the truck first. When i pulled the plug almost 3litres came out. So i left it there as that's where the axle will be while the truck will be operating. 

So are the air bags supposed to be up or down when checking the rear bottom plug. As it makes about a 3L difference
