Randy and Tim helped us out. We needed some new batteries on our trip from Indianapolis to Bend, OR. Not only did they get us the batteries, when we needed a new connection made they drove us down to the local Napa and got us back. Also stayed open an hour past closing to make sure we were good. - Dan
