If you're looking at adding TPMS to a vehicle, do your homework on the features offered. My Roadtrek on a Chevy chassis and my Jeep both came with TPMS out of the factory. I think it's mandatory now for vehicles at least up to the size of the Roadtrek.
The Chevy/Roadtrek TPMS is great. It displays actual tire pressures and only goes off when the pressure drops quite a bit. It doesn't false alarm on hot/cold days or when running down the road at 70 on a hot summer day.
The Jeep TPMS is a PITA. It only displays a Tire Low warning when any one of the tires (spare included) are more than 2 lbs off the factory set point of 35. So I usually have to adjust tire pressure when there are changes in the weather. Last time it went off it was cold outside and I had to increase the air in all the tires. Today was unseasonably warm and the darned thing went off because pressures rose above 37 lbs. Of course I did that right after running an errand, so I'll probably be out there tomorrow adjusting them again.
