recently we've had 2 trailer fires here in az. one was a gooseneck that was locked to the tow vehicle. had a golf cart inside. they went through a construction area and the batteries touched and the golf cart caught fire. the problem got worse as the keys for the lock that held the trailer to the dually towing it was also inside, along with the fire extinguishers. after they opened the trailer they couldn't get to the extinguishers so it burnt to the ground with everything still inside. to make matters worse they couldn't get the tow vehicle apart so it also went. last weekend a friend was on his way to speedworld when someone yelled that his trailer was on fire. he opened the door and grabbed his fire extinguisher, but the top part was plastic and had melted it useless. he grabbed his fuel jugs and got his super gas roadster out the back but trailer and most contents were lost.
