The problem is most pronounced when climbing grades. Your coach probably has the needed fixes. It was a design problem with the back louvers and engineering of the fan and fan shroud. On mine, they replaced the back louvered doors and the louvers in the back bumper. The fan shroud was cut back to allow the fan to grab more air, and the fan was replaced with a six blade fan. You should also check that your breather tube is long enough to hang below/behind the radiator so oil doesn't splash up into it. Also wash the outside of the radiator regularly because dirt and debris can build up over time. It is not recommended but I use my pressure washer on low pressure first with detergent and then clear rinse on low pressure. I love my coach and wouldn't trade it for another, hope you enjoy yours as much.

I joined this site just to reply to this issue. I bought a Safari Zanzibar new in 2000. I had the same over heating issues from the get go. I won't tell the whole story but I finally got it all fixed under warranty. There is more to the fix than louver doors. I can give you full details if you are interested. you can email me at davesemail@myway.com.
