pros and cons to where your pumps are located and types of pumps...
grey and black water
tank construction, location, shape, pumping out or gravity or.....
Types of heads pros and cons...
Ways of managing multiple fresh water tanks
I could go on and on.
I've read all I can find and poked around every boat I could get my hands on and have my own experiences...but to find a single
un-bias comprehensive source would be worth a lot to me in print...not DVD
and not download....PRINT.
While you’re at it do the same with elect. systems.
