I think that many big ticket products on the market (cars, boats, houses) come in a wide range of quality.
You can find really inexpensive RV's out there and they have very few features, low cost materials, lots of problems.
You can find premium priced RV's out there by manufacturers who really do build them one at a time, very carefully with lots of QC - and you'll spend premium dollars.
Or you can find a brand that is a good compromise.
I think Jayco fits that middle category of a good compromise most of the time. They mass produce these units so they make manufacturing mistakes for sure and they occasionally make design/engineering decisions we wish they wouldn't (like those brackets that are bending on many people) but even Elon Musk blows up rockets because they went just a little to light on support struts. And space is one of the most over-engineered, over QCed industries around.
Most of the time they make a solid unit. I can clean up a little saw dust out of the cabinets, and add some screws to the back of cabinets if it means I'm not paying a premium price.
But if I had a unit with a design/engineering flaw - like an underpowered slide or bending support brackets - I'd still raise hell!
I think as consumers we don't demand enough - not just in the RV industry.
But overall - Jayco is a solid product for the price IMHO.
But I'm also one of those people who's unit was almost perfect when I picked it up and is still doing fine 9 months later.
