Hello Everyone, I am new to foreforums and to the Foretravel Family. I just purchased a 2003 42' U320 with a 450 HP Cummins Red Top and a 6 Speed Allison Transmission. My Uncle and I have been looking and familiarizing ourselves with my FT and cant seem to find a Holding Tank Monitor. Can someone please guide me in the right direction? Thanks in advance for your help<br/><br/>Dan
