I use to haul B Train fuel tankers...and smoke ( ok yeah...technically illegal), with 60,000 liters ( yes 60,000) of gasoline behind me...people for some reason would get real nervous and speed past me when they saw a butt come out the window at night driving down the 401...the best was when I accidentally bounced one off a SQ police car windshield in Quebec ( at night of course...so it threw sparks everywhere)...he just pulled up beside me, turned on his inside light and shook his head. That marine tank is technically a legal fuel transportation container and the hole in the floor make for good ventilation...so probably safer than the original pinto gas tank!! LOL
