The TPMS system won't be available until March, so I doubt you're going to find anyone with any experience with them.
I found this negative in their product description: "Tire Patrol sensors go into sleep mode unless pressure is detected and the tires are rotating." That means you won't get current readings until you're underway instead of before you leave. TST will also pre-assign sensors on request, and does read before leaving. Also: "After two years, we have an inexpensive battery replacement program through the factory." TST and other brand sensor batteries may only last a year or so, but they're user replaceable at less than a dollar each. RVi does have some unique features in the "Command Center" though.
On edit: I'll just add that I saw nothing in their advertising or technical specs that indicated the sensors use WiFi instead of the standard frequencies most TPMS use. The Command Center is WiFi capable for other communications though.
