    Perfect TPMS for RV'ers!
  

*by S***E on Reviewed in the United States 🇺🇸 on December 12, 2015*

I've used the Hopkins TPMS since 2010 & always had problems with the monitor losing sensor signals as we travel pulling our 32' camper behind our 3500 RAM long-bed pickup. Upon request, Hopkins will send you an antenna extension cable that helps maintain the signal strength a little better, but it isn't a perfect solution. Also, I never liked the idea of having to purchase more sensors when the internal batteries became depleted. The old unit may be OK for a shorter setup, say a pickup pulling a popup camper, but not for my situation.So, a camping buddy of mine has this same TST system with flow-though sensors. He's used it for several years & said it maintains signal pretty solid. Based on his recommendation & the positive reviews, I took the leap purchased this one.Note: Be sure to purchase the 'TST' and not the 'tst' system. The 'TST' is made in the USA in Georgia, while the 'tst' (lowercase) is made in China.The setup was a lot more simpler than the Hopkins system. You have the option of using the power outlet plug for power to the unit or they include another power cable with an in-line fuse holder that you can wire-up permanently, which is the way I installed it. As for mounting, you have two options. There's the basic suction cup holder that sticks to your windshield or there's a little plastic tray with metal spade that slides up into the bottom of the monitor. I elected to use the tray. They provide a 3-inch strip or so of double-stick foam-like black tape that you can use to permanently attach the tray to a location of your choice. My 2015 RAM Lamarie has a small indented tray just above the entertainment center that is part of the bezel that goes around the entertainment center. The little rubber pad in the tray simply lifts out. So, I decided to use a 3M Command picture hanging strip. It comes off clean if you ever want to remove the tray. I removed the bezel (3-screws, then pull off), found constant 12VDC with ground (red & black wires) at the hazard lights connector, spliced-in the permanent power cable & ran it to the RAM's tray thru a hole that I had to drill so that I could get the small power connector through. Alternatively, I can simply set the monitor in this tray during use & stow it otherwise, i.e., not stick it to the RAM's tray. This way I can hide the little connector under the rubber pad.I found that I could walk away (line of sight) over 100' after installing the sensors & I continue to get signal with no drop out.I did find that the sensor's read out is about 2 PSI lower than the two different digital pressure gauges that I have. That's OK as I can compensate in the high/low pressure setup.I'm looking forward to our first trip in about 2-months. I'll followup if there's anything negative to report, but the way it looks now, it can't be worst than my old Hopkins unit.By the way, I decided to use the two spare sensors (only need to monitor 4-tires on the camper) for the truck & camper spare tires.

    Sensors don't fit in the F450 rims.
  

*by A***N on Reviewed in the United States 🇺🇸 on August 20, 2017*

Replaced PPro system with this because the old sensor batteries were dying, and these replaceable batteries means you don't end up buying a complete new system every 5 years. Temp monitoring was a bonus. Opted for flow-through to avoid alarms while filling. Turned out to be a futile effort. First the flow-through sensors don't fit in the hole on a 2008 F450 stock aluminum rim. Well you can get it on the stem, but it won't turn because the squareness of the sensor is too wide to allow turning it on the stem (the PPro ones were round and rubbed the rim, but did fit). Then the flow-through feature doesn't work on the inner rear tire because the sensor is too long so the input side of the sensor is too close to the outer wheel to get the pump attached. Maybe a right-angle quick-connect would work, but the angle to reach between the tires makes that difficult to sustain if it does fit. Ended up putting the front and outside rear sensors on extensions, which will likely reduce the temperature accuracy but I can turn them on the extension so they are functional. Finally, depending on how quickly the pump attaches, and when the sensor transmits, ~75% of the time it alarmed anyway as a slow leak.I do like the removable monitor so I can take it to each tire rather than having to go back and forth to the cab all the time, and it was fairly simple to set up. The stickers to mark sensor position were a problem and 2 out of 10 the paper separated from the glue side. I would have preferred a flat space on the battery cover and a white marker rather than the likely to fall off over time stickers. The power cable was "way-too-short" at 5'. I mounted it with the double-side tape to the backup camera monitor on the sun visor. Had to add ~18" to reach under the dash for power that I had already put there for the camera system (otherwise the extension would have been longer).The sensors (4 in addition to this item) on the 38' 5th-wheel were simple, and I hung the repeater on the king-pin mount. Didn't need the repeater for the PPro because I had extended the antenna to the frame under the rear of the cab and that would likely have been enough, but TST recommended the repeater for 10 sensors. The process to drop the trailer/reattach is ok, but the time to hold the buttons to get that to happen seems to be substantially longer than necessary.Haven't taken the trailer out with the new sensors yet, but they worked fine on the truck. Trip from Seattle to Yellowstone coming up. If these are a problem I will update, otherwise consider them functional with considerable need for improvement.

    Worth the investment over the cheaper units
  

*by K***R on Reviewed in the United States 🇺🇸 on August 31, 2015*

So I purchased this and it has performed very well. It does take a few minutes to dial into the sensors but then the range is plenty to hook my 30 foot 5th wheel to my truck without a booster. I opted for the pass through sensors rather than having to take the unit on and off each time I had to adjust air pressure.  A while back the charging unit migrated into the house by accident and so I didn't have it turned on. Sure enough, I got a flat and barely had time to get to the side of the highway without damaging my rims.  I can't help but think that I would have had more warning with the unit turned on as it has warned me when a tire started to overheat and  or needed its pressure adjusted in the past. The set up directions were easy to follow and if you written direction challenged the Truck System folks have a you tube video to help walk you through. I had no problem with the monitors staying on  or causing any problem with the normal valve stems for my 2002 F250 4x4  Diesel with Stock Size Cooper tires on it.  I did notice that I didn't get the Allen / security  screw tight enough on one which allowed it to turn.  Easily caught and fixed.  I keep the allen in the truck along with the charging unit which hopefully won't try to run in the house when I'm not looking again.  I looked around a fair amount before choosing this and the argument for real time and blow out monitoring along with the companies history with the trucking industry were major factors in my decision over the cheaper units that you might find.  From what I can see from other reviews this company stands behind the product too so you can buy with confidence.
