Are they any good? I have a short window to get one (3700 cu with a shelf for hauling meat) for $72. I don't want to waste my money.....

I dotn know the FIeldline. I bought a Cabelas pack frame for haulin meat, paid 129 a few weeks later they had same frame in their storees for 89.00. I havent used it yet but itll haul way more than my back will. I bet the Fieldline is similar.,

I got the Cabelas Outfitter frame and packand it works great. I used just the frame on an elk hunt and all 3 of us scored and packed 3 out in one day...all using Cabelas.
