The Prevost owners manual calls for a grease job between oil changes as part of a 6,250 mile service. How many of yall actually do this? other than Jon, of course. I called around to local coach companies trying to find someone to do it and they say they do a complete service at 12 or 15,000 miles and nothing in between other than checking tires, fluids etc.. I don't have the time or the pit to do it myself and the coach operators don't act like they want to fool with a motor home owner, unless they have nothing to do on their own coaches. I even called Prevost and got a round about answer that most owners come in for full service only. We always serviced our over the road trucks at 10,000 miles which of course included a grease job. I know off road and dump trucks are greased weekly. How critical is this grease job every 6,000 miles?
