I owned a 1997 H-41 with a series 60 and with the IFS look for the straight axle

the IFS from 1997 to 2000 was a problem with Prevost 2000 they redesign the IFS and still had problems till 2004
The 1997 model will have frame less windows nice buses but check the roof and caps Prevost is proud of the fiberglass parts for that bus BTDT
The 1st H- 41 came out in 1994 all had series 60 with the Allison B500 if that helps that is why they were built was to accept the series 60 easier than the h-40
good luck
