Always use the included bungee cords (or a cargo net) to secure extra material. Failure to do so may result in cover damage from ballooning.
- IMPORTANT: Due to the large number of vehicle makes/models and state law variations, we cannot guarantee that the cover will not obstruct rear view vision. The cover works best on larger SUVs and RVs. It is the responsibility of the buyer to ensure you are following individual state laws.
