Yes, we used a family member's address. We made sure to be entirely paperless before we set off to keep the mail to a minimum. We also kept our old driver's licenses and mostly used those at regular military or police stops south of the US. In FL we can just order a replacement license so we actually travelled with 3 total each (1 incorrect and 2 correct address), just in case. Never had an issue but having at least a second one, correct address or not, is good insurance.
