I’m basically using the same setup as Klutchdust. One way valve caps and extended dual head air chucks BUT for my dualies, I can’t use the style chuck pictured. There are two types of dual head chucks (that I know of), one that is straight with the rear facing chuck angled (pictured) and another that has both chucks at an angle. Mine is the latter. Because of different wheel and extention configurations, I don’t think there is one solution that will fit all.

I have standard valve stems, I installed valve stem caps that cover the stem yet allow air to go into the tire and use long reach air chuck and tire gauge. 
No problem. 
 Add a drop of paint pen on the rim where the inside stem is so you know where it is.
