I happen to live in Edmond and my RV dealer(Lee's RV's) had the CC converted for CHK. We have a 2008 DSDP 4304. During the week, I drive a 2009 Honda GX(totally CNG)Civic. I pay $.88/GGE for CNG at the ONG pumps across the state. My normal fillup cost is under $5.00(total not per gallon) and thay gets me about 200 miles around town.
