Encountered heavy traffic, traffic delays and construction complications as we travelled north through Montreal a few days ago on our way to Aiguebelle Nat'l park. Just north of the city we hopped off I-15 for supplies. Shortly after completing our shopping our tire pressure monitor sounded an alarm. Turned out a trailer tire had developed a valve stem leak. Not a blow-out situation but leaking fast enough that the tire would have been flat within 20 minutes. We were 1/4 mile from re-entering the interstate. Thanks to the TPM early alert we were on a side street and within easy reach of a large parking lot to change the tire. Without it we would have been on a very busy interstate with construction barriers along the margins and with who knows what unhappy results when the tire damage became seriously apparent. Given the potential consequences, the TPM more than paid for itself on this one occasion.
I’ll also take this opportunity to praise the brand of monitor we have on our Scamp
: Truck System Technologies aka TST. Earlier this year we had some issues with the signal occasionally dropping out during a trip. After getting home on a Sunday I emailed the generic TST customer service address on their website hoping I might get a reply during normal working hours the following week. In fact I had a reply within the hour asking for more information. After several email exchanges late Sunday, the representative diagnosed the problem and on Monday fed-exed, at their expense, a component to solve the situation. Truly impressive customer service!
And a final note regarding the occasionally discussed forum topic of wheel balancing. The two on our trailer are balanced but I foolishly neglected to balance the spare. After a couple hours driving with the spare (on relatively good roads) multiple items in the Scamp
had shaken loose - items that had not previously been problematic.
