Do I need to show a booked exit flight when entering Thailand on a DTV visa?

When entering Thailand with a DTV visa, many travelers report they were not asked to show a booked exit flight. Comments from users indicate that while some had their exit travel documents ready, it was not required by immigration officials upon entry. If queried, travelers can simply state their intention to leave overland, although this is also not commonly enforced. It's suggested to have certain documents, such as proof of sufficient funds, just in case.
