Have had it on our trailer for three years. The tank rank sets behind battery in an alcove in the fiberglass cap with a cover over it. It's a PIA to get to and back breaking to lift out. So purchased this to monitor levels and it works great. Only downside is the system comes with small rubber "feet" maybe 1/2" x1/2"x1/4" that fits over the rim on the tank bottom. Very easy to knock off so I just gorilla glued them on.
