RV Rental Dos & Don’ts Do: Have fun and be safe! Treat the RV with care as if it were your own. Keep all equipment and accessories inside the RV when not in use. Coil all hoses and store them in their labeled containers in the under-storage compartments. Empty the gray and black tanks before returning, and rinse the black tank hose thoroughly. Report any damage or issues that occur during your trip right away. Don’t: Don’t climb on the roof—it's unsafe and not permitted. Don’t leave any trash or dirty dishes behind. Don’t ignore any unusual sounds or mechanical issues—let us know immediately.
