From the members page > [RV booking list] > [Booking details] > [Request extension of RV dropoff date] > enter desired date > send request to the Owner. You can request in hour increments only and if the time slot is not booked already. The booking extension will be complete after the Owner approves it, so it's best to get in touch with the Owner by chat to let them know about your pending request. Note that our auto insurance will not cover you if you drive past the booked time without any extensions; however, the Owner can approve a retroactive request.
