Jon,

Your point is lost on me.

If the planes were poorly made, but flew just fine, then it appears that it
would not be that risky to buy an RV. Your statement tells me that you can
tell reasonably easily the quality of the build ("some" implies you have
seen at least 3 that you somehow decided were poorly built). Furthermore,
even those that are poor quality seem to fly just fine. More kudoos for
Van.
