Great experience!
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.

Thank you to Phil and his associates at Eastside Motors and RV.
Maybe it’s me. Where I come from I can’t get help. Maybe it looks like I’m not approachable, Maybe it’s because I am old, fat and ugly. Maybe I’m invisible. But I can be standing in an aisle at Home Depot, Lowe’s, Walmart or any other place of business that is willing to take my money looking for something

Billy
Will be coming back!
Stopped in to look at options. Wonderful customer service, we were shown several different options to give us a good idea of what we liked and didnt like. Wish all lots were as attentive and helpful rather than pushing a big sale. Definitely will be back.
