Here's a list of issues I've had to deal with in about 8 years and 70k miles of operation. Overall I'm still happy with the Discovery, despite the many issues listed below that Fleetwood might have been able to avoid if their design staff, quality assurance staff, or dealer network addressed them before we owners had to. However, several of these issues have already been remedied in later models, and I've only been forced to change travel plans once so far because of defects.
I've written up this list to help other Discovery owners keep their motorhome investment and lives running smoothly, and in no small part also to help preserve my sanity. Although I've actually enjoyed resolving most of these issues myself (being a design engineer), for many of you these concerns could be frustrating and costly to resolve. If nothing else, the following can serve as a guide in having someone else fix these things for you so you don't get unduly taken advantage of.
I've split the issues into two separate pages so the loading of either one should not cause you much of a delay regardless of the bandwidth of your connection.
Items with a leading asterisk are those that are critical: if you don’t address them, something will get worse and worse until you are stuck with a serious problem.
