I have a similar issue where my 2001 4runner has done the "i want gas" now thing so if I'm going somewhere new I carry a 6 gal in between my two batteries. You can see in this picture where it drops it:

I put it between the batteries so I still have propane plus batteries plus a little extra gas. At worst the extra gas gets me another 60 miles with the trailer which is plenty normally to find gas. If I'm really in a bind I drop the trailer then I can go another 105 miles...
I don't even strap it in; it fits so tight that I've never had issues with it even off-road. If I get into an accident I know the fuel will depart most likely but at that point that is probably the least of my problems.

There are so many things totally "wrong" about your setup..

Something about putting highly flammable liquids in a flimsy plastic gas can (with most likely the stupid EPA garbage spouts) between two potentially explosive batteries and topping that off by sandwiching between a set of propane tanks and the trailer body..
Your setup is similar to the old side saddle tanks of 70's-90's GM truck tanks in which the tanks were on the outside of the frame rails or like the much maligned "Pinto" rear tanks (which by the way, Pinto was not the ONLY car that used a rear tank.. Pretty much every car from 1950's up to 1980's had a rear tank).
Your setup is a real example of how not to do it.
You want to protect the fuel from being SQUEEZED out of the container, a plastic container is no match for 120 lbs of propane tank AND 120 lbs of battery.
A very serious accident will most likely snuff out not only you and your passengers lives but anyone else that is either part of the accident or attempting to HELP you.
A flimsy plastic gas can or even a metal "jerry can" is just not up to the task you have at hand for safety.
You are risking life and limb for what? Six gallons of fuel that will only net you a measly 40 miles of driving..
Just scary what folks are willing to do in the name of "convenience".
