RV Service near Oscoda MI

There is a cat dealer in Alpena and they work on cummins and detroit diesel also. There used to be a place in Harrisville called Harrisville Marine on US-23 (15 miles from you that did all kinds of RV repair. Bob (owner) passed away last winter so I don't know if his wife kept the mechanics but it is worth a call. Other than that it is camping world in Houghton or General RV in birch run…neither of those are close to you.
