Because the auto industry has to spend BILLIONS of dollars on design and safety.
And that gets us recall after recall and death after death do to flaws in this expensive design or better yet,the cutting of corners for a dollars sake.
Some trailers also go through extensive testing like the Jayco Eagle and it's climate control, as an example..
If these RV's were junk,there would not be so many out there that are 50 years old and still functional because there owners took care of it and fixed the little problems that happened as they happened.
Junk don't last 50 years!
