We've seen three newer Prevost passenger coaches with engine fires, I don't know the years of the coaches but were newer. That doesn't mean much.
However at a Michigan RV Resort last year or year before, We sat and talked with some Folks in two Prevost coach conversions and another brand, I don't remember. One was a Marathon Coach and another brand Conversation, was about the weak take off the 515 hp Volvo and response down the road. The 650 hp, I think, Cummins engines was being requested by some of the new Customers, plus reports of fires. It was mentioned it was probably the pollution control systems now required on everything.
