Just installed a TST 507RV on my 35' 5er and long bed crew cab F350. No repeater needed for my setup. By the time I get hooked up and ready to pull out it has started displaying the values of all the tires.
Worked great on a short trip we took last week.
I did not put sensors on my truck tires since it already has tire monitoring. But if you do, the TST has a feature where you can press two buttons (I think) and it will disable the trailer tire monitoring function but continue to monitor the truck tires until you are ready to tow again. Then you can re-enable the trailer monitoring.
