With the boating season not too far around the corner I have a question that has been bugging me about transporting my boat fuel tank. In the boat seasons previous to this, I have used a 1/2 ton to tow my 14' aluminium fishing with a 20hp outboard boat. When I went on fishing trips, I would toss all the equipment in the back of the truck including the fuel tank. I figured that is was safer to carry the tank in the back of the truck since it's in an open area, and it doesn't bounce around as much as the trailer. Plus, since the boat does not have a flat floor, I figured this would save the boat hull from damage and dents. <br /><br />This year I have a new tow vehicle which is a station wagon. I am worried that it may be unsafe to carry the fuel tank in the back of the wagon because the cargo area is shared with the passenger compartment. Even though the tank is sealed, I still worry about vapours or the possiblity of disastor if I ever got into a car accident. At the same time, I am worried if I keep the tank in the boat, it will damage the boat hull since it will just be on the thin aluminium hull and the trailer bouces around quite a bit on rough back roads.<br /><br />So what's the best way to carry my fuel tank when I am pulling the boat with the station wagon? Should I fabricate some sort of "fuel tank holder" that would be secure enough to keep the tank in the bouncy trailer and not damge the hull? Or am I being overly worried about carrying the tank inside the back of a wagon? <br /><br />Any is advice appreciated.
