LONG POST, SORRY!
My stems are not 180 degrees but are at same location. It would be difficult for 180 degrees due to 5 openings in wheel; one would be totally blocked from accessing. I read on ford trucks forum that Ford recommends 180 but they all seem to come from factory in same location for some reason. I may consider rotating one of the tires with my next maintenance to see if it helps any with accessing.
I'm altering my TPMS system to accomplish what I desire without using extensions on the TV. I'm going with the non flow-through sensors on the outer wheels as they are too long to access with an air chuck as shown in pic. The flow-through sensor will fit on the inner wheel and I believe I will be able to get an air chuck in there to air the tire up. It should be easier as it doubles as a valve stem extender in that position. I will test this later today. I really don't want to use an extender with a flow-through sensor as that just creates too many areas for leakage, defeating the purpose.
I will go with the basic sensors on the TT as the flow-through sensors are just too long and protrude too far from the wheel. One brush against a curb or airborne road debris will snap them easily and there goes the air. It defeats the purpose of the system if you become MORE vulnerable to an air leak.
To summarize, I will use flow-through ONLY on the inner wheels of the dually as they double as an extender and are fairly protected from getting hit by debris. I will use the basic sensors on ALL outside tires of the TV and TT (total of 8 basic sensors) as the stems are easily accessible. I won't use the locking mechanism as its unlikely anyone would steal them. Its simply an allen wrench key anyway.
Before I do anything though...unfortunately I have to return the system or talk to the tech support for the TPMS 507 system. I've had the system for 2 weeks and no sensing is taking place from the TV even from 5 feet away. The sensors from the TT transmit sporadically if at all. Its taking up to 45 minutes for them to be detected and then are dropped after a few minutes even when standing a few feet away. Very disappointing as the system worked perfectly for 2 weeks.
Picture 1 is TV rear outer with flow-through on
Picture 2 is TV rear outer without flow-through and inner with
Picture 3 is TV front with flow-through on
Picture 4 is TT with flow-through on
Air chucks will not fit on pics 1, 3
Today will check to see if air chuck will fit easily on pic #2
Protrudes too far from TT on pic #4 ( requires short extension as base of sensor isn't deep enough to fit on stem without air leakage)
