Does anyone with the Blue Ox RF brake remote also have a TMPS in their motorhome cab that works without interference?

Most of those systems use the Industrial, Scientific and Medical (ISM) frequency bands around 430 MHz or over 900 MHz. AM radio is 0.530 MHz to 1.6 MHz. There shouldn't be any interference at all unless it's coming from the innards of the device itself and not the sensors.
Try wrapping the control head in aluminum foil and seeing if it goes away. It's also possible that the interference is traveling up the power cord and into the vehicle wiring. That is usually a fairly simple fix by putting ferrite beads on the power wires or finding an inline filter.
If you can power it from a separate battery see if that makes the interference disappear.
