If the piccalo only weighs about 23 to 25 lbs i dont see the big deal about carrying in on the back. a pack frame with a shelf on the bottom would be ideal. I have carried more equipment on my back than 25 lbs. between my duty gun belt and my ballistic vest i carry that much weight on a daily basis and have done so for 35 years . I woudl think the concept would be to get a pack frame that handles the pounds.
