Although I personally wouldn't choose TorC, all of the southernmost towns at the lower elevations would be suitable choices: Deming, Lordsburg, Las Cruces, Alamogordo, Roswell, Carlsbad, Hobbs.
My first choice would be Las Cruces. There are RV and trailer parks between Las Cruces and El Paso that would afford the best opportunities to partake of what both cities have to offer (including Juarez, MX).
