JMO, but the benefits of an internal system don't outweigh the hassles. In fact, TBH, I don't really know what the benefits would be, maybe the fact you wouldn't need metal stems?
Having played with three types of external TPMS sensors on my Sprinter RV (6 wheels), I have a different opinion. The external sensors are much easier to install, but they can be a hassle when adding air and even with metal stems can create problems with leakage and sometimes broken stems. I finally gave up on TPMS but if I wanted to get back into it I'd opt for the internal sensors. I've had factory installed internal sensors on three different vehicles now and the only issue I've had is having to replace them when the batteries finally expired.
Now admittedly installing (and maintaining) internal sensors is more difficult than externals, but typically once they're installed they should last about 5 years before needing battery maintenance.
