I just installed 6 TST 507RV Tire Sensors on the Toad and 2 front tires of the MH. I will install sensors on the rear tires next week when the weather clears.
After a little learning curve on setting the sensors to be read by the monitor, I tested the sensors on the Toad by using the monitor while driving a couple hundred miles around the area going different locations on the Interstate and city roads.
Once set, it works great. Now while towing I don't have to be too concerned about the tires, if i pick up a nail etc.
I received the initial shipment from tst in 3 days at a temporary address. I will receive the additional 4 sensors today 3 days after placing the second order.
The car has short rubber valve stems. They are situated with enough clearance that they do not rub against the wheel covers while running down the interstate. However, when I get a chance, I will probably change out the rubber stems for metal.
The MH has steel tire stems. It was a little challenge getting them on the front wheels due to the location of the tire cover. I needed about 1/4" to be able to install them without hitting the wheel covers. I talked to a tech at a local trucking company, and he told me I could carefully bend the stem. He indicated that is what they do all the time on the big trucks when installing them. I used a rachet and socket as he suggested, and very carefully bent the stem the 1/4" needed for clearance.
The monitor picked up all 6 tires within seconds and as I monitored them during the day, the heat from the sun caused a change which was recorded on the monitor.
I am convinced and confident that the system works as advertised.
One more toy, but an important one. I did a lot of research on tpms systems over the last year. I think they all may be comparable, but I went with the tst for the ability to change the batteries myself, and their reputation for customer service.
The sensors are lightweight and easy to install with the special wrench sent with the package. They sent 2 wrenches, I keep one in the car and one in the MH.
Good Luck with your choice.
