I would move back to Reno in a second if I could get the right job there. Just have him make sure he can afford a house on his salary. I lived there before the real estate crash, and watched house prices in my neighborhood go up about 100k per year. The proximity to California may mean the prices are still relatively high. Gas prices are probably also higher than average, but there's no state income tax. (Good for your paycheck but obviously not so good for things like keeping schools open, etc.) I rented a two-bedroom duplex for $800 and was able to get by on much less than his starting salary.
Mt. Rose ski area is 30 min away from town, Lake Tahoe is about 45 min, and the whole wide emptiness of the Great Basin stretches out to the north and east. I used to run a dirt path along an irrigation ditch, and a 15-minute hike from that parking area puts you in a National Forest wilderness area. Yosemite, Mono Lake, Lassen, and SF are all within a half-day; Death Valley, Redwoods, and Great Basin NP are an easy day's drive. There's a road course in Fallon and a drag strip near there if he's into racing.
Dallas climate is like H-E-double toothpicks compared to Reno. The weather is nothing like Las Vegas, as people often assume. It's almost always cool at night, and you could make it through the hottest few weeks of summer without A/C. Many houses have swamp coolers rather than air conditioners. Winters can actually be cold but snow rarely stays around past noon on the valley floor. Yearly precipitation is around seven inches if I remember right, and humidity is next to nothing. The meteorologists must get tired of saying "sunny and dry." A chance of rain means it might sprinkle somewhere across town for a few minutes. If he plans to travel much in winter, especially toward the Sierra, he should have snow tires or chains.
The biggest negative I ran into was property crime. I was ripped off three times in the first year (stolen license plate, tools out of my pickup box, and mail), after never having been robbed before. But the positives far outweighed that the longer I stayed.
If he likes sunshine, a dry climate, and outdoor recreation of the mountain and desert variety but not huge cities, he should love Reno. Obviously, it's not the place for him if he's shown any inability to stay out of casinos. If he's from Florida, he might have trouble getting over the color green, but that's just temporary.
