In planning a long trip to Northwest National Parks, I'm a bit concerned of running out of gas. My Highlander normally can achieve 24 mpg, when towing it is more like 12. That makes for many frequent stops to be sure there is enough in the tank. Are there rules for attaching tanks outside the trailer? Can plastic be accepted? Only looking at one of those 2.5 gallon. Willing to go metal but only found 5 gallon sizes.
