We are relatively new to this forum and we have read several posts regarding what has been described as bad service/support from Keystone and or dealers.
We purchased our Cougar last October from Mike Thompson's RV in Colton, CA and have been really pleased with the unit although we have only made 3 relatively short trips to the coast. We recently had an issue with one of the slides and took the 5er back to the dealer for repair. The service we received was simply great. We informed the service adviser of our upcoming trip and he went the extra mile to insure our Cougar was repaired without any undue delay.
The only issue we had was convincing him that he didn't have to wash our trailer before we picked it up! Considering our buying experience and, now, our service experience with this dealer, I would not hesitate to recommend them to anyone! IMHO
