I currently have a single propane tank mounted on the tongue of my 2006 Fleetwood Santa Fe and am getting ready to install a second. I have seen the dual regulator kits with auto switching but was looking into doing it differently. Rather than spending $40 on this kit, is there any reason why I can't buy a 1/4 NPT brass tee for $2.49 from Home Depot and an extra Pigtail? I'm not worried about being able to fill one while using the other or about running out of propane on a trip. I prefer to have them work together as a single tank. Since I haven't seen anyone mention this way of installing a second tank, can anyone tell me if there is a reason why it won't work?
