What to check first
Check for visible gaps and photograph staining after rain. Do not cover a wet wall with new sealant before the source is known.
When to get help
Request a leak diagnostic and any trim, seal or substrate repair as a written scope.
Your RV’s make, model and component instructions control. Stop use and seek qualified help for propane odor, smoke, active electrical danger, unsafe braking or other immediate hazards. This guide does not diagnose your RV or establish part compatibility.
Next step
Check the exact component manual and model number before following a model-specific procedure.
