Can anyone see why a fuel tank 2" Deep x 35" wide x 36" long wouldn't work laying on the rear floor?

It would be more then 10.5 gallons so would double my range And take up minimal cargo space done that way.

With my electric fuel pump already mounted on the back of the Riser it would be simple to plumb A simple valve could be used to keep the fuel from the higher tank passing in to the main tank.

Granted it would mess with a rear seat but could easily be made to handle any cargo that might be stored in the back. 

And as my rear floor is perfectly flat save the rivet heads I could easily put down some rubber strips to support it.

Hi Mark,
It's own vented filler cap where you can get to it?
How much expansion room does it need for heat build-up?
How do you tell when it's empty or full or half-full?
Some way to drain it when need be?
Need a filter for accumulated crud?
Cargo on top includes folks stepping on it?

I can tell from your posts you want extra range badly.
A trailer with extra gas cans (along with all the other stuff) necessary for extra long-range excursions?

Just my 2 cents.
Good luck!

Its own vented cap yes that would be easy
as to expansion room I doubt that would be an issue especially if I were to just put a long neck on the filler tube.
As to knowing the level. Who cares burn it off first and then your on the main tank. And it could be checked with a stick like half you guys do anyway.
If I hooked it into my Electric fuel pump setup at the back of the main tank A drain would be easy to Tee in same as a filter I could just add another Summit 40 micron mesh prefilter to the line leading to the pump.
CHUG will have an Aluminum hard top by spring. And no way could anyone stand up on the floor once thats in place. No one has stood up in the back since I was working on the roll bar anyway.

But all good discussion points.

Yes I will have a 16 gallon Mustang fuel tank in the bottom of my little off road trailer. I have a brand new one sitting in the shop just waiting.

I'll also be able to carry 2-3 5 gallon cans

Consider relocating the muffler to a passengers side (MB style) set up - you might be able to put a gas tank under the floor where the stock muffler goes.  It would take some doing but that would keep the rear cargo area open.

How about something like the "Tokyo Tanks" that the B17 Flying Fortress used back in the day?
Make a rack to secure and connect them to the fuel system only when you need them.
Take them out when you don't.

A pair of these economical 6-gallon Marine grade tanks have built-in fuel line connections, vented caps, and even a fuel level gauge:

True but due to their shape would take up most of the cargo area of the jeep

A pair of Rotopax 4 gallon tanks would only be 3" high if laying on the floor. But to be honest I don't trust the plastic. And I am sure they would not due well with cargo on top of them so I would have to add a layer of something to support the cargo. While an Aluminum tank with a few baffles and 1/8" construction would hold a lot of cargo weight. I could space the baffles in such a way that there was a top to bottom support every say 9" and that would only be 4 baffles
