You can get extended valves on the rear tires on Amazon ($20 for two) Amazon.com: Pacific Dualies 18101 MAX EZ Air 7" Braided Stainless Steel Valve Stem Extensions with Small EZ Wire Clip For Ford E350/E450 Dually Trucks RVs Motorhomes with 2" Round Vent Holes: Automotive
It very easy to connect them. Advise you to take off original plastic connector (you can get a loose air in that plastic - I got that problem one time).
For front tires you don't need any or you can get for 10 bucks this:
Amazon.com: Pacific Dualies 18045 45 Degree Valve Stem Extension - Set of 2: Automotive
I think it going to be more convenient to check air with this connector.
