Last year returning from CAF, we noticed the axle on our trailer was smoking. We pulled off at the first exit in Ohio and, sure enough, we had a major problem.
We were at a loss as to what to do and then noticed a sign for a trailer company. We happened pull off at an exit with the largest trailer sales company in Ohio right around the corner.
Since we needed a new trailer to get home (it would take a month or more to get our existing trailer fixed), we thought we may as well upgrade. All's well that ends well (although it was an expense we certainly could have done without).
