We recently bought a "Crown Club Qualified" used coach as Lazy Days and I can firmly say you get treated royally. Especially for the initial delivery, where they will take the time and do everything needed to make you satisfied with the rig (whether new or used). The service is more personal than the regular and the Club campsites and amenities (e.g. free breakfast, lunch and Happy Hour) make the inevitable waiting much more pleasant. They really bend over backwards to make you feel special. As to whether the service is actually better in a technical sense, I'm not really sure. However, the techs are their top guys and they do seem to have a genuine "do the job right" attitude. Example: We had one problem that did not exhibit itself when the coach was in the service bay. My personal service adviser took me to talk to the tech and I said I could show him the problem when the coach was on my site (it was the leveling jacks), so the tech came AFTER WORK when the coach had been returned to us on our site to see the problem. The next day he came back, took the coach to the shop and fixed it. In the regular service dept, I would most likely have had to make another appointment to get further work done and appointments at LD are scheduled weeks or months in advance.
Coaches are designated as Crown Club eligible models when they are new, based largely on the base MSRP (currently around $300k) and their position in the manufacturers hierarchy of models. The decision is made by LD management for the class of coach and not on each individual sale. For x number of years, any subsequently sold coach of that year & model, whether new or used and regardless of actual selling price, will be eligible for Crown Club treatment. You might choose a non-Crown Club model and actually build the price up beyond the CC threshold by adding options, but that won't make it a Crown Club coach if the model was not pre-designated by such.
