Just bought first camper - lot of questions - can you help?

First off hello -

1.) We discovered last night it came with a full HOLDING TANK. I think that is the poo tank right? Where can we go get that emptied and flushed out?

Hi! Are you sure the holding tank is full? The indicator lights on our tank say 3/4 full all the time, even when we've just emptied and flushed it, so we know for certain that there's NOTHING in that tank. So if you're thinking it's full because of the indicator lights, it might be empty. But I'd certainly take it to a dump station to empty and see! :)
