How long should it take to replace a timing chain cover gasket?

What is your question?

My truck is a 2016 F250 superduty with a 6.2L gas engine. the dealership says they will need the truck for 2 days to change the timing cover gasket. This seems a little odd for this job to take 16 hours?

What makes this problem better or worse?
