Hi Steve,
Our motorhome is also a Burstner that we've had from new, and it is now 4 years old. I love it as much today, as the day we bought it, but it hasn't been without problems. I can relate a catalogue of disasters perpetrated by 3 different dealers here in the U.K...I thought I had found a good one in Camper U.K., but then they disappointed me big time recently (If you want to know more contact me on Private Messages..I am not going to slag anyone off on a public forum)
We are members of the Burstner owners club, and all our problems have been resolved through them, directly with Burstner in Germany. Have you contacted Burstner direct? We have found them to be very helpful.
I don't think there is a motorhome on the market that doesn't have problems, it's how the problems are dealt with that matters..and U.K. dealers are not good at it.
Jackie.
