They do indeed still have full hook-up rental spaces for travel trailers! We have a 27’ and we were fine (maybe call if you are one of those big fifth wheels to be sure). Terlingua’s a funny place in the best way possible so your not gonna fine incredible signal or high speed internet in these parts but my husband was still able to work full time online from here. The owners are super sweet and her art studio is worth checking out. We walked to a bar every other night and it’s easy access to hike Big Bend daily.
