I've found over the years it is the large massive plant varieties that bear fruit on the interior of the plants. Our humidity is even lower than yours so the evaporation effect keeps the interior of the plants much cooler than outside temps. Like your climate the plant also has to endure early spring nights of low temps then handle extreme heat during the summer months and start again for a fall crop. This cross Chris allowed me to trial has been a great variety for my climate. Not to mention these f2 seeds each grow something different.
One of my sons just moved to Albuquerque from Las Cruses this year and he's still trying to adjust to your climate with his small veggie patch.
