Everything in any RV eventually works loose
. I go through once a year and check/tighten everything I can find. Plumbing, electrical, drawers, cabinets, jacks, etc.
We have had several rigs where the plumbing was loose when we picked it up. Nothing like taking your first shower and stepping out of the rig to water and suds
