As for the macerator pump, we've had the same one for at least 15 years that we use on our 30 year old Wilderness trailer that is pretty much permanently parked at a membership campground. Always does the job of getting the spooge from the black water tank to about 60 feet to a tote that I can take to the RV dump nearby.
It helps to have an 18 inch section of clear 3/4 inch hose connected to the discharge hose so you can be sure the spooge is getting pumped. Also best to have a clear 45 degree elbow on the 4 inch hose for the same reason.
