I had all sorts of headaches form the hose type extenders that came on my MH
ended up buying some rigid extenders, 5-1/2 inch, for the inner tires
along with a set of those rubber flange stabilizers.
I fought with one of these extenders not playing well with my TST TPTMS transmitter, but otherwise they have been good.
My preference i think would be duallyvalve set-up, but that requires demounting the tires.....
