I just picked this up at Costco today for $90. It's almost 15 gallons. I think it's a bit more expensive than jerry cans, but it might be a bit more versatile, especially with the nozzle feature. Costco is the cheapest by almost $30 on this. I like it because it will sit flat in my SMB trailer, so I might actually pick up another one to have for deep baja trips.
I am in the same boat with my Chevy, it has a 31g tank and transfer flow won't touch it. I can have a ~50g tank added where the spare went for $1100, which seems excessive both in size and price. So, I'm going to give this poor man's version a try. Just filled it up along with my tank and 2 jerry cans in TJ, 50gallons for $110.
