TST saved my Bacon in December heading to Alabama for the Winter.
Heading through Tennessee I noticed a slowly dropping pressure on the trailing axle right side tire.
When I got into Pelham, Alabama, South of Birmingham I stopped at an RV park where I've stayed in the past and ask to use a pull through site so I could run my 120 volt air compressor.
I was granted permission, and brought my tire pressure back up.
I was down to 100# at that time, luckily it was a slow leak.
I could find nothing in the tire.
Spent the night in Greenville, Alabama, refreshed the tire in the morning before we got back on the road, and checked again for a nail or something, found nothing.
When we arrived at our Winter RV Park, pulled the wheel and took it to local tire dealer.
I had a cracked rim.
Called Heartland, she emailed me a picture of the rim, which I confirmed.
Heartland had to order it from Tredit Tire.
It was sent to me and tire mounted on new rim.
I would have never known about the low tire pressure with out the monitor system.
I was able to monitor the situation and safely arrive at our destination.
Without the TST monitor, the results would not have been good.
The results of this tire issue I realized I needed a 12 volt air compressor.
I checked on the forum and found what Cookie, & Jon and a few others were using and purchased a Viair 12 volt compressor.
So from my experience, get a tire monitor system & a 12 volt air compressor.
Happy ending.
