I bought new from the "older very taciturn man" (who has since passed away)14 years and over 100k miles ago; no issues with him or the company philosophy, and very few issues with the Ford E450 or the coach build quality of the Lazy Daze.
I've seen the issues with many other class C brands; most are far newer than my 2003, and most are riddled with multiple, ongoing/unresolved quality problems. They're overweight, poorly designed and engineered, and sloppily constructed with cheap materials.
Lazy Dazes are not perfect, but if there's an issue, the factory stands behind its product and fixes it, unlike a great many other manufacturers and dealers. Lazy Dazes are not for everyone; they don't have slides, the price is the price, and the factory is not "Burger King", i.e., they're "factory direct", not a "custom product" operation. If a customer wants a new LD, s/he will wait for almost a year for delivery; it's a small factory, and it sells within its production capabilities.
Good used LDs do come up for sale, but finding one requires a lot of searching and patience. There are also plenty of old, poorly maintained or outright neglected and abused LDs that come on to the market; don't assume that just because a rig is an LD, that it's a good buy. *Poor maintenance* can turn the highest quality rig into a leaky, beater POC pretty quickly.
If I were to buy a new rig - no plans to; this one is hardly broken in! ;) - it would, without question, be another LD.
