Or,
Borg Dually Valves which are now being sold by Camping World.
This is an iPhone/Android, Ford/Chevy, Coke/Pepsi debate if there ever was one. The important thing is to get one-piece all-metal valves on ALL SIX (or Seven) Wheels! You want your tires easy to check and air loss free.
Some kits are 4-wheel (rears only) and some are 6-wheel (added nice but unnecessary angled front valves). Again, ALL METAL, ONE-PIECE Valves from Steer to Dual to Spare!
A few of us use other solutions. Some have found alternate suppliers at less cost. I happen to have looked long and hard and did not find a solution till Phelps Tire referred me to Six Robblees and they carried BORG.
I support BORG because it's what a major truck supply group carried, what I've used without one hiccup for years, and because when I carelessly damaged one, I was able to reach Bill Falkenborg on the phone and he had a new valve in my hands, cross country, the next day.
Bill and Chuck are good people making outstanding products. Their parts will serve you continuously and unfailingly. Pick one.
JUST DO IT!!!
