What is Difference Between TST Tire Pressure Monitor Systems # TST-507-FT-4 and # TST-507-FT-4-C

Question:

1- It appears the 2 sensors listed below are identical except one is color and one is grayscale, correct? 2- Does the color change to yellow and red so the warning is more noticeable on the screen versus the grayscale monitor? 3- I will be towing a 2 axle travel trailer with rubber valve stems these should be fine with this trailer, correct? 4- I also have a 2 axle boat trailer I should be able to either move them from one trailer to the other or purchase 4 additional sensors and use the same monitor correct?

The two kits you mentioned are basically the exact same with exception being the color of the display. The # TST-507-FT-4-C has the color display that puts the alert messages in red if there's high or low pressure as well as temperature whereas the gray scale # TST-507-FT-4 would display everything in the same gray-like color.

Either kit works great on rubber valve stems. For the second trailer you'd need additional sensors with # TST-507-RV-S4 and you'd be able to use it with the same monitor.
