We drive that route too, it's beautiful. Last year we stayed at Whiskey Flats in Hawthorne clean showers and nice folks, nothing fancy and I don't remember a pool but all in all a nice place http://www.whiskeyflats.net/
Hey yes jella I'll second that, Whiskey Flats is my stop going to BRC from Santa Barbara, CA, too! Good big grocery store a short walk away and right by a fuel station.
Coming home I stop at the Boulder Creek RV spot just south of Lone Pine. Very nice place with pool and spa even! http://www.bouldercreekrvresort.com/
They have complimentary muffins for breakfast yum =)
Both places sell propane too.
