Always inspect:

• Seals around your doors and windows as well as the roof where ever sealing is evident. Sealing material should always appear clean and soft as well as completely covering the gaps. Dry, dirty, shrunken seals will let in water and cause damage.
• Dings, cracks rust etc. in all surfaces and lenses.
• The lights and make sure all function and all appliances work as they should.

Don’t hesitate to call your repair shop if something doesn’t seem correct. There are no dumb questions only informative answers. If RV mechanicals is not your forte, take the unit to your dealer. Many will not charge you to make a quick visual inspection of your unit and advise you if a more in depth look should be made.
