Since my dolly requires 90 psi in the tires this won't work for me.
It just happens I also have the ACME dolly which, as you say, has 90 psi in its tires. The TPMS I have is the Tire Minder which can monitor up to 22 tires. Each tire can be set to whatever pressure desired. In my case I set the front two tires to 100, the four rear tires to 100, the dolly to 90, and my Mini Cooper to 45. Any of the 22 tires that I do not set a pressure to are not displayed on the monitor. To keep things intuitive I set it up such that the graphics on the display "look" like the configuration of all the tires. This way when reading pressures it is easy to tell which tire is being read.
By the way, when towing the dolly with no car, set the dolly tires to 30 psi so the dolly doesn't bounce (this I was told by the factory).
