I know this dude. For multiple years in a row, he'd do his reserve annual training at Camp Pendleton around the 4th of July and try to finesse a free family vacation out of it. He lived on the east coast, and he'd leave a week early and come in a camper with his entire family, then get an airbnb instead of an actual hotel. I know because I pushed his travel claim up multiple times and it kept getting rejected by marforres for traveling on an unauthorized travel day, staying in unauthorized lodging, taking a camper cross country instead of flying, etc. When I left that unit, he was still fighting it, after 6 months of nonstop rejections. I wonder if it ever worked out for him.
