So, I'm at that point where I'm ready to pull the trigger on a TPMS for our 5ver (I know, I'm late, but better late then never!!) and really need some good advice on which system to invest in. I've been really looking at the TST507RV with the 4 Flow Through sensors, but the price keeps creeping up and up. I'm not sure this is the forum to put this in, but thought I'd throw it out there and see what the opinions are with regards to any system that I should be considering. Thanks in advance. Paul

Sees to be concerns over flow-through sensors propensity to leak. Once you have a TPMS, you stop accessing the valve stems unless there is a leak, then you know and can get it fixed right away. We've have an EEZTire system on our class A for a year now with excellent results with the non-flow thrus. Agreed that the price has been escalating since we got ours. Usually electronic stuff gets cheaper. Even at the higher price I'd gladly do it again. I'm a firm believer that all RVs should have them. Pretty much all travel in an RV is for a longer period of time than cars. With a car, you pick up a nail and when you come out of the store your tire is flat. With an RV, you drive long enough for the tire to leak down enough to overheat and fail at speed. This is a safety regulation that should become law for RVs as most people don't realize how RV travel makes a blowout more likely than in their car.

I purchased the model 507RV with flow through sensors from TST a couple of years ago. No problems at all, and the system saved my bacon last month when I had a tire going down. The system alerted me to the problem and I was able to pull over to take care of it before the tire was completely flat and started separating which would have caused a lot of damage.I wouldn't travel without my system now.

I have and prefer the smaller standard TST 507 sensors. With the security covers removed, they are even smaller and lighter, and removing them to adjust air pressure is then no different than removing standard valve caps.

Would a pair of cameras looking at the tires be less fuss than a TPMS?

You'd have to watch them constantly.. TPMS have audible alarms that warn you before you'd be able to visually tell something was amiss.

TPMS - I know, again!! Need some buying advice!

Of course you have already searched this Forum for `TPMS' then possibly searched the results for the make/model you might be interested in, right?

I just installed the TST 507 with flow thru sensors,so far irs working great, got them online from clicky
Best price I could find and quick service.

TST hands down. Quality and the customer service is unbelievable. Just call them about product. They will work out anything u have issues with. I had issue with picking up signal or I had interference. They sent me a repeater out on loan to see if that was my problem. Great down earth people

Only problem I have ever seen posted about the flow thru sensors is that air flow can be slow when you are adding air. And they are somewhat larger than the non flow thru.

I have had the non flow thru for 5 years and am very happy with them. I typically add 3-4 pounds of air at the beginning of each travel season and never have to add air again until the next year. Have never had a tire lose air. As noted above, removing the sensor to add air is little more than removing a valve cap.

I did get a repeater as occasionally my monitor would temporarily lose contact with a sensor on my 35' 5er.

I have the TST flow-through sensors and if I had to do it again I would give them a pass. They are a real PIA if you have to add more than just a couple psi since they are very restrictive. I have had no issues with leakage. I take them off if I have to add air, which kind of negates the whole idea. :)

The only thing I have against the TST system is the excessively long time between losing contact with a sensor and being notified of that. It can take up to an hour to be alerted that the monitor has lost contact with a sensor.
