Im looking at getting a Trekker 65, 180 dollar external frame backpack. wondering if anyone has any experience hauling meat with one? I know its an older style but it seems solid. Money is a big issue and im going on my first elk hunt in 2016. I know its not a ton of bag space but can I attach a tag bag directly to the frame? Also I will be mostly a day pack but it will double as my meat hauler if we can get an elk on the ground. Any input would be greatly appreciated.
