We have a 2001 Kountry Star (36ft, two slides). Bought it new and still love it.
Had two issues in the first year and both fixed under warranty. Actually both issues were freightliner. Haven't had any issues since.
It also has the ISB 300 (Cummins 5.9) Living in Oregon and going to the beach (towing a jeep Grand Cherokee) we are often in the coast range mountains. I had a Banks system installed and it runs great.
Increased HP and torque significantly. Ran okay before but towing the jeep slowed it down in the mountains.
Don't think you'll go wrong with a Newmar product. Great customer service even if it's just a phone call asking questions.
Would buy this unit again in a heartbeat.
Due to depreciation the above opinions are now worth less than what you paid for them.
We are all good at something.....
I just happen to be a good bad example.
