Spent the night at the Marfa Lights Viewing area. Parked right behind the "Gone with the Wynns.com" coach. Wanted to stay another night but it was just to cold for boondocking a second night. So we left the nex morning. Made it almost to Lobo, and heard a quiet boom followed by rattling, and lost power. Pulled into a picnic area and waited for a tow from Coach Net. Currently seating at Rocky Mountain Cummins in El Paso. Lets hope the damage isn't to bad for the pocket book.
