Sigh. This is the kind of obvious, simple, sensible answer that I feel silly not immediately considering.
The only downside (shared by my initial thought) is that they aren’t collapsible. So that volume is committed even 1/4 way through my trip

I’m curious if these are legally allowed in Canada. If so they seem decent!
I'd also search out "off road" people and forums, though they may not specialize in your vehicle, they probably know the various rules and regulations.
https://www.zuksoffroadcanada.ca/Gas-Tank-15-Gallon_p_997.ht... does exist, so I'm sure there's things out there. People modifying vehicles for Nunavut or the Australian Outback would be places I'd start.
So do things like : https://masterhitch.com/catalog/truck-suv-accessories/auxili... but I'd be a bit wary of bolting gas tanks to the rear bumper/trailer hitch myself.
And many rules will stop applying once you are "off road" whatever that means in your area.
Your alternative is of course to fill some plastic bags from your local grocery store like this [1] lady did.
