Unfortunately there is not a upgrade program for the monitor.
Sorry, but I do have the new model in stock if you’re interested.
Thanks

TPMS Questions

I'm getting my equipment figured out for the start to my 'Great Adventure' of 5th Wheeling. Based on suggestions in this post, I'm planning on getting a TST 507 system. My trailer (Montana 3121RL) needs four sensors, which the basic TST comes with. My truck (2015 F-250) has the factory TPMS, which doesn't give the actual pressures, but just alerts for low pressure (not sure when). Is it necessary to add four sensors ($$$) to the truck, or will the factory system be sufficient? Any thoughts are appreciated.

Regards,
John

Id leave the truck be as it will warn you already, and just go with the ones for the trailer.

We have never lost a signal with the TST 507 and we do not use a repeater. That is 14 years and two Montana's . We are 53 feet long truck and Montana. We do keep the monitor up high so that the antenna is visible through the windshield.

I would suggest the non flow thru sensors . IMO the flow thru are a bit bulky ,and stick out further then I like. If you need to inflate, or deflate ,the non flow thru are not an issue to remove. Otherwise they don't have to be removed . I turn on my monitor, let it boot up, and see if all the tires are still inflated properly, and set to go. No need to check with a gauge.

Also with the flow thru I believe they do require steel valve stems because of their size. Although a lot of us do have the steel valve stems running the G rated tires .

To answer your question , I wouldn't worry about additional sensors for the truck, you already have a low pressure warning on them . My truck just tells me what my pressures are, no warning on the 3500 Rams, the 2500 Rams have the low pressure warning. I take a look at the screen to see what the truck pressures are, if okay I'm good to go. My thinking with a sudden blowout non of these sensors are any good, so with the truck I am not too worried . I can check pressures periodically if worried. The only concern is a slow leak, and you will have a warning on the truck.

All kinds of things can cause tire problems, with all that weight on the back tires, I have them on all 10 as I want to know if the truck tires are heating up as well, not cheep but niter is the damage caused by a blowout.

A few thoughts about some of the discussions;

I have the TST 507 system. It was the older model with the black/white? screen that I had for years and was near impossible to see in the daylight. Received my new color monitor day before yesterday and went out yesterday evening to set it up. I just left the sensors on the tires although it said to remove them and it worked fine. I tried turning it so the sun was shining into it and seemed much brighter. I'll get it in my truck and see what it looks like but seems to be much better than the older one.

I mounted my repeater in the front compartment right above the batteries and just connect/disconnect when we travel. Has worked flawlessly. Previously my right rear tire would drop out about once each travel day.

To 55 Bel Aire's question of adding sensors to the truck, IMO opinion I would. The little yellow low tire alert is OK but really non informative to me. It could be down 2 lbs. or flat - and which one you don't know. My previous trucks had actual pressures for each tire and a little warning light comes on if one is low. With the individual pressures I know which one and how much. Adding the TST system with the color monitor will be great but for added safety and comfort I would just get the 4 additional sensors when equipping the trailer.

I've had really good luck with these guys:

The additional sensors are a little spendy but they should last a long time. Proration over several years makes it very worthwhile IMO.

I installed TST 507 Last night after agonizing over the factory option from Ford.

So far I am impressed— specifically the ability to add an additional three trailers (which I will do).

Not having cables and it’s tidy compact size are all pluses at the moment.

That's not like mine. Our 507 came with the repeater and I did not install it. The display is on top of the truck dash and some of the 5r wheels would sometimes loose connection. I finally installed the repeater with a switch high above the battery enclosure in the geny room. all good all the time.

The TST 507 will connect to up to three additional trailers. I am anxious to do this for the boat, horse and dump trailers. All (obviously) much shorter than our 41' 5er... so I am hoping I can order caps and not use an additional repeater.

Just wanted to provide a little update;

For those considering upgrading from the older, non color monitors to the new color ones as I just did I found out today you need to have a repeater. My old unit did really well on the bumper pulls with an occasional drop out without the repeater. I installed the repeater due to that and it cured it.

Today I had to take the MHC to the dealer; at trip of about 60 miles. I did not turn on the repeater just to see what the new monitor would do without it.....nothing! It lights up and cycles tires but never got a pressure from any of them - I was really surprised. I called TST after I dropped the trailer off and they said they would have thought it would pick up a sensor or 2 but yes "the sensor in the new color monitor is not as sensitive as the one in the older monitors and DOES require a repeater to operate without issues".

I know some folks run the older units without a repeater and they work fine. Just wanted to make sure anyone in that situation and contemplating the upgrade knew there would be an additional expense.
