My husband got his DTV on the advice of Thai immigration at BKK because he was going in and out of Thailand so frequently. He told them that his company is in Dubai but he goes back and forth to Thailand when he doesn't physically need to be in the office in Dubai. For the visa application he had to show all the required documents, but also he wrote a cover letter explaining his work situation that when he has time off he prefers to come back to Thailand and while here he communicates with office staff and clients online. Maybe you could include in your letter that while in Thailand you would be corresponding online with people at your work. It's worth a try. Not everyone has the same work situation so don't listen to people on this group chat that claim to be certain that you wouldn't qualify for the DTV.
