From Amarillo, Texas, we headed west and then north into the mountains of northern New Mexico — a five-hour drive that climbed steadily from the flat Texas Panhandle to the high alpine country around Eagle Nest at 8,300 feet. The drive itself provided an early complication: somewhere along the route, either diesel fuel contamination with water or the rapid change in altitude was causing the engine to run rough under load. Purging the fuel filter helped, but a visit to the Freightliner dealer in Albuquerque was clearly going to be necessary. We filed it away and pressed on. What was waiting at the end of the drive was worth every mile of it.
