OK now, why does everything have to be so difficult?! I have a '62 Tradewind, and am trying to pour the antifreeze into the outside water hook-up. The fluid will not flow into the trailer. When I blow into the hose conection there seems to be a certain amount of pressure to overcome before anything flows(my breath). All of the spigits are open in the trailer. I can find no other way to get the antifreeze into the tanks either. I can't unscrew the valve at the outside conection nor the plug in the end (none on the top) of the cold water storage tank. Does the antifreeze have to be pumped in with yet another specialized piece of equipement?!!!!!! HEEEEELLLLLPPPPP. Maybe well worth $50 to have someone do it for me.

Maybe worth it. But I'll be willing to bet that if you hook up a vacuum to just one faucet and close the rest you can draw the Antifreeze in your tank. Don't need much any way.
