While there are probably exceptions, most all RV manufacturers have had to deal with quality issues because of the pandemic. Getting parts has been a problem, and many long time workers retired or found other jobs.
As a result, Lance had to replace a number of their long time workers with new people. It’s a learning curve for the new people! Consequently, there has been an interim where quality has been affected. This is mostly small things and not construction items.
Hopefully all of the issues you are dealing with are easily fixable, so can enjoy using your nice camper 😎
