I do have a couple of complaints. The hose included with it is way too thin. You will want to replace it immediately. The brilliant designers of the tank think it will naturally vent through the RV’s system while filling. Maybe in theory but not in practice even with a perfectly straight hose. They did provide a capped outlet on top too which helps but if you purchase the optional fill indicator, it goes in that outlet and you lose your venting! They need to either build the fill indicator in or add another vent.
For those who want to know, it was purchased at Camping World.
