RV anti freeze

[camato5]

I know it is kind of early to be worried about it but I have a 2014 Thor Tuscany 40 XTE and last year I blew out the water lines to winterize it. There is a connection in the wet bay that says fresh water/ antifreeze. I was wondering how I get antifreeze into the water lines of the coach when winterizing. My 5er had a hose with a valve on the water pump and I just stuck the hose in the jug of antifreeze, bypassed the filter, opened the valve and turned on the pump. Is there a fill hose somewhere buried behind a panel I need to dig out or do I need a hand pump.

I'd suggest checking the owner's manual first, but look behind the panel, they often tuck the suction hose up behind the panel.
