Gasoline requires some care.

There was a person recently carrying gasoline in a plastic container inside their vehicle. the gas ignited because of an electrical spark ... the container was not grounded. the interior of the car turned into a blazing inferno. the person was killed because their lungs were scorched.

I admit that scenario is very uncommon. but it did hapoen.

I always carry gas containers on an exterior rack. But the suggestion of a small high quality traler is a SUPER GOOD idea.
