Thanks everyone for your input. It is always good to hear others experience with a particular firm. And yes, I understand the need to be aware of the hidden maintenance issues as the seller usually does not want to reveal ALL potential problems as it would just reduce the potential selling price.
On another note, do you feel that an oil analysis is warranted before purchasing a used coach with several years of use? Heard of one owner that was having his engine use water on a regular basis, not much but regularly, and eventually caused major problems with the engine. Evidently an oil analysis would have picked up on this and could have been fixed as a minor repair instead of a major repair. ??
