My 2018 Ram dually came with long rigid metal inner valve stems like joegpetro is talking about and the viair has a long metal chuck, works great. With almost $150K in combined truck and 5th wheel, can't imagine why $293(cost now Walmart online) is such a problem to keep all my tires inflated properly, even took me all day to put 80psi in truck tires before viair
