Flat Tire Repair on RV Trip

We knew it would eventually happen traveling so many miles and let me say I'm so grateful Steve is so handy. We found out we had a flat when we pulled in to our campground. It didn't make a noise or make the trailer pull, we clearly must have gone quite a distance because the rim is done for. Both Steve and I had a feeling about tires all day but didn't do anything about it. God was totally telling us to pay attention. We originally looked into a tire pressure monitoring system and put it as a later item to purchase.... guess what we are going to buy soon in addition to 2 spare tires. Any recommendations for a TPMS? Live and learn 👨‍🔧 Luckily there was no damage to the trailer and other then taking an hour to change it out, no harm done.
