Best TPMS?

As for the inner dually there are extensions that will bring them out with the outer dually. I am actually the one who located what is now called TST (Truck Systems Tech) years ago. It was being sold out of Colorado and since I was looking for a system that showed PSI and TEMP, I bought one and posted the info on here. Well, a lot of folks liked the system and ordered them, the outfit selling them got overwhelmed and started charging the customers prior to shipping to them while he waited to get them from his China Supplier. Needless to stay he went under. A gentleman out of Texas jumped in and took over the exclusive distributorship and even covered those of us who had the systems if we had problems. A relative of his acted as the CEO of TST in their headquarters. While they owned TST the customer service and prices were great up until it kinda dropped in customer service when the new owner made some employee changes. During this time I believe the service was not what a lot of us where used to. Now that they have a previous employee back it is heading back up to it's reputation. The EEZE system looks to me like it's basically the same as TST when I looked at it in one of the Yuma Swap Meets a few years ago. I noticed recently that a Forum TST had on another RV website is now closed, why, I don't know.
I have been running the 507 system since it was first available and have had few if any problems. I have a 39' Tradewinds and I did need the repeater. Batteries are easy to change when you have to do it. Currently I have one sensor that since I changed the battery on it it won't pop up on the display. This happened once before and when I drove the MH it showed up. Why? I don't know. But in my opinion either TST or EEZE (?) would be a great choice
