I don't know where vicsryd got the comment:
"Western RV (e.g. Alpine) shut their doors at the end of April because they got stuck with hundreds of bad chassis that couldn't be fixed."
I own a 2006 Alpine, have accumulated nearly 30,000 miles, and have been very close to their issues and many other Alpine owners via the Alpine Coach Association. Let me state that the last thing Western RV had was any problem with their chassis. The Peak Chassis they made is one of the smoothest riding, best handling chassis made and the common quote among those who own and drive an Alpine is that "Nothing drives like an Alpine". And chassis problems have been very rare, almost unheard of.
WRV may have had trouble generating cash to stay afloat, but they built a very-well liked, extremely well-handling coach that has a very loyal group of owners. Most of the quality problems with Alpines have been with systems they didn't manufacture, like HWH, or radiators, that they assembled into the coach, and many of these have been fixed by the component suppliers.
They had a few problems with their cheaper Avalanche version a few years ago, but they didn't make many of those coaches.
So from an owner's standpoint, I don't know where the bad chassis comments on Alpines came from. They are great machines, and I, like many Alpine owners, plan to keep ours.
