I've had some estimates to have a SeaLand 711-M28 self contained marine head with a 9.5 gallon holding tank attached. It would be connected to my freshwater supply and claims to use 1 pint per flush. Complete unit sells for about $600 and $400 to install. Any feedback on their quality?
SeaLand 711-M28 install?
