I think if I were carrying that much fuel or water in a dink, I'd use a flexible bladder, and I'd pump the fluid up/down, rather than try to lift it in/out. We did this, sort of, last week, with a few of those flexible, 5 gallon drinking water jugs, plus a 6 gallon water jerry can. I looked at bladders on Defender, and you can get them for fuel or water in just about any size that suits you.
