Quality Decline since Covid

Prior to covid, most mid model year models were pretty good. Early in a model year things were iffy due to the learning curve for the different design. Late model year units were victims of boredom. We had a starcraft that was a mid year build and was almost flawless, a forest river that was an early model year and never made a trip that didn't have something go wrong and our keystone is a mid year build and it had a loose water line discovered at the pdi and fixed immediately and no other issues on six trips. I have made many upgrades but this has no bearing on build, only on features not designed in.
