Dual wheel tire pressure monitor

[jamesr3406]

I was wondering if anyone has a aftermarket device to install on the dual wheels of a F350 to monitor tire pressure?

A TPMS with two pressure sensors at each dual pair, or Crossfires between the dual pair and then just one pressure sensor on the Crossfire.

I've use Crossfires between the dual pair and one TST pressure sensor on each Crossfire. I hated dual tire pressure checks until I tried this arrangement - 5 years now and working fine.
These are the ones I use - other makes/models are available:
Crossfire: Crossfire - Dual Dynamics
TST TPMS: 507 Starter System Kit - Starter Systems, Tire Pressure Monitoring Systems - Truck System Technologies

So I have 2 crossfires (back left and right) and 4 TPMS (front and back; left and right)
