We bought our first TPMS system for a long trip we took it out west. It was great peace of mind.
Just recently we took our usual local trip five hours south. On the last hour of our journey we noticed the pressure in the tire dropping quickly. We pulled off at a gas station to find a nice long nail sunk into our tire! Had we not had the system we would have been clueless to anything being wrong.
So I guess I would highly recommend a TPMS for your camper, I am a believer!
This particular system at first didn't seem to go on as smoothly as people suggested but now that we have installed it and we understand how it works we would recommend it. The numbers on the tire caps rub off with the first trip but we just numbered them with a permanent marker and haven't had any problems. The actual monitor is sometimes difficult to read. With your sunglasses on it makes it somewhat difficult. We actually put the protective plastic back on because that somehow made it easier to read monitor than when we removed it! That is probably my only complaint.
At the beginning when we were having issues we contacted the company and they responded quickly and stayed connected with follow up until we were happy. Pleased with their customer service.

I installed the system the day after it arrived and had no issues at all. As other reviewers have recommended, I read the manual first and made sure I understood the install procedure.
The very next day we set off with our travel trailer on a week-long vacation, and the TPMS system worked flawlessly. In fact, before we set off on our return journey home when I turned on the system it began warning me of a tire which had low air pressure (it had lost 14psi during our stay at the campground). I always take a portable tire inflator with us and so was able to put air into the tire before setting out, but I wouldn't have been aware of the problem without having had the system installed. This has given us more confidence with regard to our safety when on the road.
My wife and I are very happy with the product and would recommend it to anyone.

Product is mostly as described, but that "130 foot" claim is bogus, at least in real-world conditions: With the receiver on the dash of our pickup it doesn't always immediately update the display when pressure changes in the trailer tires, which are only about 30' behind the receiver. It does update from much further away if there is line-of-sight between the tire and the receiver, but what use is that? It's still useful because with turns on the road it will always eventually update, but I'd still recommend a repeater-based system if detecting rapid changes (i.e., blowouts) is a critical feature: Our truck and trailer are small enough and I'm sensitive enough that I'd notice that from the handling, but if you got a huge rig and/or little seat-of-the-pants sensitivity this probably isn't the system for you. You can't beat the price and ease of installation on this, though, if all you need is slow leak detection (which is by far the most common issue, and what I need it for).

Finally was able to take my travel trailer for a trip and had this hooked up. Worked perfectly and was able to monitor both the tire pressure and temperature at a quick glance for the whole trip. Seller sent a couple of emails making sure I was able to get the sensors set up correctly and that I could reach out if I had any issues. Because I was able to monitor all 4 tires during the trip, I wasn't anxious the trip on how my tires were running.

Still waiting for Amazon delivery, but received this from Seller. I believe this would have been appropriate to include in the product description page. Will update all other evaluations, later.

Hi wwwwwww,

Thank you so much for your purchase for Hieha Tire Pressure Monitoring System! This email is to ensure proper delivery and satisfaction.

Note Before Usage: Sensor and Display Connection Guide:

1. Install the antenna first.

2. Hold down and press the power button for 3s to turn on the display.
Ensure the display is in 6 rounds interface and then install sensors.

Common Problems And Simple Trouble Shooting During Installation:

1> Not In 6 Rounds After Power On. Press the '+' button and the Power button at the same time to switch from 4 to 6 rounds first and then install sensors.

2> Tire Pressure Data Keeps Flashing After Installation. It indicates that the tire pressure value of your vehicle exceeds our default high/low tire pressure alarm value. Please manually adjust the alarm value until the data stops flashing.

3> Data Not Displayed After Installation

A. Rematch the tire sensor that is not displayed.
B. Start the vehicle and drive it for 10 minutes.

4> How to rematch the sensor ? Hold down and press the '+' key for 3s to enter the matching setting mode. Continue to press the '+' key once, the tire icon flashes, press the 'M' key to select the tire position where the data is not displayed and install the sensor, then the monitor will display data promptly.

5> The "˜X' icon in the lower left corner of the display is the alarm symbol for the repeater. When it alarms, it means that the signal from the repeater is a bit weak at this time.

6> The black rubber O-ring is to prevent air leakage from the tire when the sensor is installed. Note: Each sensor already has an o-ring installed inside, and the extra is used as a spare replacement.

Hope you have a pleasant time shopping at Hieha Store. Any questions please feel free to contact us and we will get back to you ASSP!

Best regards, Hieha After-sales Service ---
