all good tips... so when I get to campground, regardless if I have a sewer site or not, is there a chemical that I add to both the black water and gray water tank? how is this chemical added? and do you re-add this said chemical everytime I flush the tank? also, when I leave, and I do like crimps says and flush and dump both lines, do I add more chemical to the black water holding tank when I get home and park the camper? im assuming that when I get home the tank will be fully empty, do I still keep some water in that tank while its sitting for a few weeks? and now the dumb question of the year, how does one dump a black water tank when not at campground? im talking end of year before winter when im cleaning everything, how do I clean out the black water tank at home?
