Off the Escondida exit there is a narrow underpass with a 13.9 height. We did okay with our smaller camper trailer. Big rigs may want to seek another entrance. We were only here for a few hours to drain our tanks, refill and fix lunch. No problem with electric or water hookups. We noticed that water on spot #5 with RV hookups is capped. Train tracks are nearby. It is beautiful and very quiet when we were there.
