If I know I'm going to be staying on location somewhere (for an extended period of time) and then venturing out during the day to film, I'll bring WAY more than I need so I can switch my bag up on site, that way I can still travel light and bring what I need, but switch my loadout if the day calls for something different. AKA, I'll bring my 70-200, 12-24, 50mm 1.2, 200-600, 16-35, and 24-70 but when I actually leave to shoot I'll only bring 1/2 of that. I also make sure that I can fit everything in my carry-on which isn't too hard, it's just heavy!
