Answering on a Sunday really is customer service.I guess they get it realizing us rver's do travel on Sundays and can have problems on those days just as well as any other day. Great product that just saved me a lot of headache when it alarmed me with a low pressure tire.
The flow through sensors allow you to check air pressure manually with a gauge if needed and add air without having to remove the sensor. TST 507 saved us when we picked up a new rig a couple of months ago. One of the tires was 30 PSI. The monitor went off just as we were ready to leave the dealer!

I don't have flow through. The sensors give me the pressure without a gauge. The Sailun S637 tires require air so infrequently sensor removal is not an inconvenience. Unless I'm going to be away more than a month I don't even bring the compressor. Even then the only use of the compressor has been by others.
I also do not have the flow thru. I typically add 3-4 lbs air in the spring before I put my sensors on. And never have to add air until the next spring. Have never had a flat or even a low tire on the trailer.
The flow thru sensors are a little larger and heavier than the standard sensors.
I can't really see an advantage to the flow thrus on the rv as it is so infrequent that i have to add air to the rv and the sensors come off real easy to inflate. If you plan on installing on a dually then i can see the advantage to the inside wheel if you can air it up without having to remove the sensor. I change the back wheels from 55 psi to 70 psi when towing but the front tires and the rv keep the same pressure year round.
