My previous class A had valve extenders (the stainless steel type on the rear dully's. They were nothing but problems; detached from mounts, leaky valves, sidelined on more than 1 occasion. The extenders that came on the RV were too unstable and moved around a lot so I ditched them.
On my 2019 fr3 30ds, I installed the DL3FC's. Specifically ordered these:
Dually Valve Stems for Ford F450, F550, F53 with Steel Wheels Hand Hole Oval 4.25"x2.25" - DL3FC - Dually Valve with Front Stems
Got them from shinyrv.com ($115) and here is a link

I installed myself on all 4 rear tires and took a few hours. Had to take off each tire and break the tire bead (look at youtube how). Could have gone to tire shop but too much trouble to schedule appt and bring in.
Happy with install and added tpms sensors. Attaching a few pics after install.
