Yeah, good advice. The one time we broke down (serpentine belt) on the highway (I-12 north of New Orleans), our service dispatched a tow truck which was to take us to a certain place. I called the business which was an RV sales lot (no diesel mechanic). So when the tow truck arrived I asked if he would take us to another business I had called which was a big truck repair shop. He said, "I'll take you anywhere you need to go." I feared I might have to pay, but it was actually at the same exit as the other place and just across the highway. Score! So he got us there and we were able to get our rig fixed.
