Eagle Gas Inc at 8445 Los Coches Road, El Cajon, California.

Super nice staff that always greet with a smile and make it a point to get to know their regular customers. It's real busy in the mornings during the week because of their price on gas, so you generally wont have luck getting a propane refill. Understandable with the amount of people coming through before work. Google says they are open 24 hours, but I'm not sure about that. I just called to verify and did not get an answer. I'm heading that way to see if I can fill up propane for my RV. We shall see!
