Gary is correct about factory warranties, however most of the stuff in an RV is warranted by the equipment mfgrs not the RV mfgr. (AC, furnace, microwave, stove, blinds, reefer, slides, etc). The hard part about an RV mfgr that has gone out of business are the proprietary parts such as chassis and structure and structural/manufacturing defects. So those with Western RV motorhomes that had their chassis may be in a fix. Aside from minor gripes there isn't much to go wrong with the structure unless you have an accident in which case your insurance should cover and you can find places that can repair or have a supply of parts. For example, when I had a tire blowout on my Alpenlite 5th wheel, I was able to locate replacement fender skirts even though Western RV had closed its doors.
Bottom line I guess is that, if you can find a good deal on a RV manufactured by a quality company that has gone out of business because of the economy, I wouldn't worry too much about the mfgr's warranty. Do a very thorough pre-buy, get the dealer to fix any glitches you may find and go for it.
