Auxiliary or Larger Gas Tank

[RickBullotta]

I’ve been thinking more on this. I’ve looked at a 30 gallon marine grade bladder that can fit inside my existing roof top box mounted on my existing after market cross rails.
I would only ever fill it to 18, maybe 20 gallons of premium (about 6.3 lbs/gal) to stay within rooftop load limits. I see 165 lbs in owners manual.
I would cut a fuel dispensing line hole on drivers side of box with protective rubber inside the cut hole. Also would cut some vents into the box for summertime use (can reseal with tape, whatever for winter use..).
Under the bladder inside the box would be a special absorbing blanket for any small leaks during refueling and refilling. Also maybe some lightweight cushioning foam underneath all that.
The box keeps the bladder safe, locked down and hidden.
Then stop, open top of box, feed refuel hose out and down side to GX filler door, and insert hose (possibly with aid of a hand filler like at a gas station), open valve on bladder and add roughly 9-10 gallons to the GX. Would test initially with gravity feed..but there are portable, explosive proof small pumps for that if needed.
When ready to refill bladder I would pull up with pumps on right side, climb up, open box top, open bladder refuel cap, get down and and grab fuel pump handle, step up and refill as desired.

I still need to test out my existing cross rails and also my roof top box on the GX. And need to more closely measure inside of the box I have.
Have to think about it some more.
Likely I missed something here. What do you think?

EDIT: even cheaper option for me is to buy say 4 of the 2.6gal rotopax style cans and see if they’ll fit inside my box. Cheaper, easy to use, but less space efficient, and they tend to vent odors worse than a pro style bladder.

Two 5 gallon/20 liter Wavian cans. The plus is that they DON'T vent. No vapors to worry about as long as you close them correctly.

Has anyone tried filling up the passenger compartment with Gasoline as a reserve? Thinking you could leave the sunroof cracked just enough to fill it - then all the gas is 'self contained.' What could go wrong?

Wonder what Sticker Fab could make for that after it cools down?
