I am not familiar with your Pleasure Way but the easiest way to check if your starter batteries are being charged when connected to power is to measure the voltage across their terminals. It should change from less than 13V to more than 13V when you plug in IF they are being charged.
As for sewer hoses, I would get one that has the screw on connection to the campground sewer connection. More and more campgrounds are requiring a sealed connection. This sealed connection can be attained with a screw on connection or the use of a rubber donut.
