Short answer, I think it would work but, depending on how you pack but as I have said elsewhere in other threads, I think it is best used in daypack mode with the occasional need to haul.
Have done warm weather (non hunting) overnights with mine. 28 liters fills up fast. You can use the load shelf feature and add a camp bag to extend volume but then you have an issue with packing meat if you get lucky.
It is a great pack and frame idea but the pop up isn't a replacement for a full size frame and bigger bag, if you are going to be hauling big loads with it a lot. The frame works but it isn't as stable as a full size frame. Shoulder straps, waist belt are also scaled down too. They work but I just wouldn't want to make a habit fo using it for big loads. If you want something with the same capacity to serve as a hauler more often I would look at a mule or a pintler.
