Ok, let's all calm down and play nice, and if you can't, go camping. Seems we're all getting winter blues.
As for removing the tank, I'll give you a generic, as I have not worked on a wolf pup.
What looks like the tank mounted above the cross members, is and isn't . One of the cross members will have angle brackets, and screws going through the side of the frame, and is removable. This is usually the rear one, cross member, but not always. You can remove these screws, remove the cross member, and then the tank.
Make sure the tank is empty. Make a diagram of the wire colors and sensor location they are on. If you can, unbolt the drain valve, rather that cut the pipe, saves a coupler and gluing back later. Shouldn't have to remove the toilet, but may be helpful.
