I've got another way to look at build quality. Compare PC to other manufacturers.
From my experience there is NO comparison. Now this also has to do with a time tested design and quality control. PC has a great system and it isn't the hectic mass production of other manufacturers.
I'm selling a 2020 Cyclone which is one of the quality brands of toy haulers. They use the more expensive materials but very few screws are actually put in straight and the overall construction, cabinetry and design are not up to the standards of PC.
A friend just bought a 2019 Tiffin Open Road for more than I paid for my house. He has had nothing but problems with roof and plumbing leaks, broken levelers, fireplace broken and problems with 110V. He can't even use it.
