Tire pressure / temp monitoring system...

Do you use a tire pressure monitoring system on your TM? Who is the manufacture? How has it worked for you? I have searched the forum some and read the input from Cali Camping and Rocky Mtn Ray. I am going to purchase one in the near future and am looking for real world input from any of the forum members who have one. I have found several choices on the net but place more faith in our members if you know what I mean.

Thanks much and Happy Camping!
