Back Black Tank Removal - Twin/Kings take note November 13, 2013, 09:48:45 pm Yahoo Message Number: 143600"http://www.coxontool.com/index.php/Travels/20110510" Interesting read. Just about every T/K have been under has had loose holding tank bolts, including a couple where the clamps were not in place. Other models can have loose clamps too, something to check occasionally, along with the body-to-frame, propane tank, generator and step bolts.Larry
