I've had a Marathon and now have a Country Coach. I bought very little from either converter, because I get most things from other manufacturers. I got a full set of manuals with the CC and the Marathon.

My Country Coach was always serviced at Marathon and Prevost in Texas before I bought it. Marathon even did a major redo of the bedroom which involved matching the interior materials, and they did a great job. I think in most cases the "What Ifs" are worse than reality. Ya'll quit picking on the CC crowd!
