Dually Wheel Inner Valve Stem Cap Fix 5 6 2021

The first time owner of a vehicle with Dually wheels to include it being an RV, getting to the inner valve stem to fill air or remove a stem cap isn't easy.
Replacing the stem cap is tricky also....to using a 10 inch long piece of rubber tubing allowed easy reaching back inside and screwing the stem cap back in place.
Would imagine the reverse will be done as easily!
