I have put thousands of miles on my TT with the STS system on it and it does the job quite well. I like the color monitor, easier to see even with sunglasses on. Also thank you guys for the excellent support when I needed it. I am a Techno RV fan !!
We live full time in our 8 1/2 ton 5th Wheel with 4 dogs and 4 cats. With my entire home and family on-board, safety is a big issue and a TPMS was a must.
Our Ford truck has an existing integrated TPMS but the kit for integrating the 5th Wheel's tires was $600 plus installation.
While I did not want yet another monitor on the truck's dash to make it look like a "star wars" cockpit, installing a top-rated system at half the cost of an OEM option was compelling. As it turns out, the small but easily readable color monitor of the TST system fit neatly in a center-console cubby, with the friction mount holding it at just the right angle to see it. You don't need to stare at your tire monitor while driving but if we hear an alarm sound it's easy for either one of us to glance down to see what's the matter.
Installation and set-up was easy and intuitive with the help of TechnoRV's "Learning Series" videos that come with their products. Their videos are well produced, making them easier to watch than many YouTube "instructional videos" made by some joker with a selfie stick.
Our first trip with the system was our mandatory evacuation from Coastal GA in the path of Hurricane Dorian. We were a bit frazzled and stressed with all the unknowns bearing down on us, but it was comforting to have the TST system in place and monitoring the safety of our home on the road. While we luckily did not have any tire troubles, the system worked as promised and made it easy for us to keep informed.
Our next purchase will be a dedicated RV GPS system and we will favorably consider the offerings of TechnoRV based on the service and support we have received thus far from Eric and Tammy's crew. I like their business model and appreciate their firsthand experience.

I went with four of the caps and two pass thru sensors. The pass thru sensors I used on my inside dualies. I eliminated the braided valve extenders, they always seemed a little sketchy to me. With the TPMS I do not have to go manually check tire pressure before each trip. Woohooo!
I really like the quality of the TST 507 kit. Color screen. Easy programming. My only complaint is I wish it charged off of a USB-C cable (it uses Micro USB)...minor gripe. It comes with a suction cup mount and the grey, grippy stand shown in this photo. I probably would not use the suction cup mount except that the grey stand is great for a smartphone.
Talk about a quick turnaround!! Ordered this and a VIAir compressor. Both units came in 2 days after ordering!! WOW!! Thanks Eric! We got them both mainly for a lengthy trip in October, so haven't had the opportunity to use it yet, but plan on setting it up for a short trip next week. Looking forward to updating the review after we return from the October trip.
This was an easy upgrade and installed with no issues. I do not need the repeater on my rig which is 36’ plus the length of my truck. The only improvement I would like to see would be simultaneously monitored tires which would alleviate a potential 30-40 second delay in the tires. Not a dealbreaker though.
Installed this on a new fiver before our extended summer trip. Ran with the factory tires (risky, I know). I want to get at least one season out of these tires before upgrading. Kudos TST.
I've waited a year to write this review. This TPMS system is awesome! I have 12 tires monitored with my TST 507. It will give you peace of mind while traveling. There are too many things to be concerned with while driving and having the TST takes one of the major concerns off your list. TST's customer service is second to none. I had to call them a couple of times and they are patient, friendly and knowledgeable. Watching the Techno RV videos convinced me that this was the right unit to buy and I'm glad I did. I mounted the TPMS repeater with an on/off switch to a project box and attached it to the panel in my black/gray/fresh water compartment. That way I can turn it off and on when I'm connecting and disconnecting the lines. Thanks TST and Techno RV!
Customer service is awesome, had a issue during programing of the sensors. I called the number on a Saturday and got a person and the issue was on me, go figure. When you buy from them they Email instructions and videos which are better than what comes with the unit
Everyone at TechnoRV were extremely knowledgeable and helpful. Shipping was extremely fast. I had a technical question in which they followed up on quickly and with the information that I needed to resolve the issue. I Would highly recommend and will use again.
