ISB 300 Power loss / Turbo Failure
I have a 2004 Newmar Kountry Star with 69k miles. It's been a great coach and I have had no problems to date. On my last trip I noticed significant power loss, especially when climbing hills or tak...

Unfortunately I have bad news since I am the turbo expert being as how my now sold 2009 Safari Cheetah with worlds biggest POS Caterpillar C9 blew through 4 in 40000 miles. Luckily mine were all under warranty but it seems you will not be so lucky.
They told me the turbos went out due to not idling to let them cool off even though I idled 5-10 minutes each time I shut motor down. Then of course they told me that my emissions system kept going out due to too much idling. If you can't tell, I am fed up with diesels.
Anyway, based on my experience with replacing 4 turbos, expect approx a $7000 bill if you have a rear radiator coach. May be cheaper for side radiator because of ease of access.
