Roger,
Check the winterization sticky at the top of this sub-forum for the full details on winterizing. Most TT's and 5ers have (but not all MH's) have a hose located right near the pump that is open at one end. Put the open end in a jug of antifreeze and turn the valve on that hose to open, and the valve on the hose to the FW tank to closed. Now the pump will draw from the jug instead of the FW tank.
Also, strongly recommend opening the low point drains to empty as much water as possible before sucking in the AF. (And then remember to close them again before starting the AF - ask me how I know...) If you use the AF to push out the water, you will dilute the AF and probably use more. You will also have more liquid in your waste tanks that might freeze (low %age of AF) unless you empty them again before storing.
ETA: Just like Crabman posted one minute before me with pictures and all
