I started off with the TM-55 and gradually added 12 sensors to it. 7 for the truck (dually and spare) and 5 for the 5'r (4 tires and spare). Upgraded to the TM-66 monitor that used the same booster as the TM-55.
I did not like the antenna's on the TM-55 and TM-66 being extending and stow able. Was always fearful i would bend or break them. The TM-77 had a short fixed antenna that i do not need to worry about. The TM-77 screen is about 25% bigger overall than the TM-66. Easier for us old guys to read. I do like the way I can separate the trailer from the truck on the TM-77 so I do not get alarms when using the truck locally.
Was pricey to get up to 14 sensors (2 spare) but I feel what I have spent on the system is worth it so i do not have to worry about a tire going flat or overheating. The system did save my bacon once with one of the metal valve stems worked loose and lost enough pressure (65psi down to 50 psi) to sound an alarm. I was able to pull over, identify the problem, tighten the external nut so I could make it to the next exit. At the next exit, I fired up the generator, plugged in the small air compressor and filled the tire with air.

That's one of the main reasons I got a TPMS, you can check your tire pressures religiously before you leave but you can't know what's happening as you drive down the road unless you have a monitoring system.
I have the TST 507 with the standalone receiver with no booster and all the sensors report with no problem. I love the piece of mind driving down the road and being able to glance at the monitor and see what's happening. Of course not having to crawl around checking tire pressures is pretty sweet too.
