I recently saw some tire pressure monitor caps on a friends motor home, and he said they were great for speeding up the frequent checks he performs. His were from TireWise, but I found and ordered a set of Tire Pressure Monitor caps from the following link from what appears to be exactly the same type he had. I actually ordered a set for the RV, TV and Trail-Aire Pin Hitch. Very reasonably priced.
