Gas can mount on top of spare tire on back wall of trailer

Scott, I appreciate your point of view. But an ordinary bump won't budge this thing -- it is six feet off the pavement, and a bumper-thumper won't affect it.

A big impact will, though.

So my question is this: is this arrangement any different from a tongue-mounted gas can? It is virtually the same as the jeep cans that carry gas racks on the spare tire -- I see those on SUVs every day.
