Regarding the holding tanks, especially the black (toilet)......be sure to leave the valve closed until the tank is at least 3/4 full. It is only a holding tank and if you leave the valve open only the fluids will drain and you will end up with the "pyramid of death" . Also, use plenty of water when flushing. Be sure to use a septic approved paper such as Scotts single ply.
After dumping the tank, flush it well with fresh water and then treat the tank with an approved product of your choice.
Enjoy your new life and home....you will be cozy
