If you're stuck in traffic, slept in at the campsite, or for whatever reason going to be late returning the RV, it is important that you let the owner know as soon as possible. It is important that you give as much notice as possible in this case, as owners may need to make alternative arrangements. Think of it as the same requirements for checking out of a hotel on time. If the RV is considerably late upon return, the owner reserves the right to obtain an extra fee from your bond.
