Does anyone know WHERE to locate cylinders for a Beaver Marquis (2000)?  We purchased this coach from prior owner and after waiting for it for better part of a year, received it just 2 weeks prior to our scheduled first x-country trip.  Upon delivery, the seller / prior owner advised that the left rear hydraulic needed to be replaced and he would do so upon our return.  Well, we were gone 2 months and have been back for 3 months ... and it hasn't been done.  Supposedly the part is unavailable.  This was a very bumpy excursion for 5000 miles that we'd prefer not to have again.  Any information will be greatly appreciated.  Thanks.
