Im interested in purchasing a 2005 Thor Mandalay 40B / 20,000 miles / Freightliner / 350 cat. My questions are. Is there any owners out there of these with any advice or input to what they think about the quality and reliabability of the units? What milage will something like this get? The previous owner has several issues with the unit and I was wondering if this is the norm with the breakin on these coaches. Has anyone had any experiance with Copley,s RV Service Dept. in Hobe Sound, FL? I am thinking of taking the unit there for some issues the current owner is having.
