What Our Customers Are Saying

Great Service!

Our propane stopped working while on a trip from Kansas City to Alaska. I stopped at Eastside and they were very helpful. A Tech even took time to help me make sure I did need a new regulator. We were able to make the repair and get back on the road. - Mark
