You can do a search and read about somme of the experience I had with my TST. It took awhile to get it all up and working, but I will say one thing, the company was great to work with. I put the repeater in the engine compartment of my tow vehicle. I kept loosing a couple of tire signals, so at the suggestion of the company, I took the stub antenna off the monitor located in the motorhome and replaced it with the remote antenna. I had the remote antenna in the side window and still had problems, finally moved it to the center of the windshield on the motorhome, and everything works great now. The remote antenna has a long wire so you can move it around to various locations. For some reason, according to the company, my problems were very unusual, but like I said they worked with me. Almost a year after I bought the original unit, it was the one where you can't change the batteries youself, I was at Quartzsite and talked to them about my ongoing problem, and asked them what they would charge to switch to the units with the replacable batteries, they exchanged it out and didn't charge me anything, still didn't help the problems I was having, but it's all up and working great now.
