Misery Loves Company, I guess
My 600 is plagued with camper-related issues (the Crafter itself is brilliant thus far) and in Spain it's all but useless to try to get it fixed by a dealer. I'd be "happy" (relatively speaking) to take it at my expense to a competent independent technician but that would invalidate my warranty.
So, I depend on the shared wisdom from some wonderful and knowledgeable people on this site. I've learned a lot. And it helps that I've been able to enjoy the camper in spite of its issues. I'm trying to keep a sense of humor about it. I will take it to Germany before the warranty runs out in August. Maybe I will fare better there.
I'm thinking that one of the RV builders (Knaus, maybe) who offers a MAN chassis (same as a Crafter) might have been a better choice- plus you can get 4Motion on the smaller, 600-size, chassis.
I rarely see GC's on the road or at campsites but I did see one at a spot in Croatia. The camper came over and said hi. A Polish chap who, as it turns out, is an engineer at the factory that produces the Grand California in Poland (he was using a factory GC).
I didn't have to say a thing before he apologized for the lack of quality control and poor design choices...
