Should I purchase an RV warranty?

I guess it bothers me that we can out a man on the moon but RV manufacturers can't seem to be able to put out a consistent product. They keep going up in price but with the AC units fridges roof issues you think there would be some form of quality control. Now do I expect them to build industrial type units, of course not but unfortunately it seems like unless you spend over 90k your essentially getting some lower end fit and finish. I still have a chance to purchase the ext war but to be honest after the fiasco of a buying process and essentially being lied to multiple times I may seek something from good Sam directly or shop around.
