Winterizing DX3

I know this seems like an odd time to be thinking about this, but here goes:

What's the expected hookup point for antifreeze on the DX3?

In the spring when I got caught with a cold snap I disconnected the hose from the tank and let the pump pull out of a bucket but there's got to be an easier way than disassembling the bed every time.

Currently thinking about adding a 3 way valve and a hose under there that could be accessed from the panel under the W/D. Also wondering if there's a way to get a hose/valve down into the wet bay and keep the anti freeze out of the bedroom altogether.

Thoughts?

that is the expected hook up point. For whatever reason, we get little to no complaints about the winterizing process. Maybe the truck owners are just more resourceful, aren't winterizing or have someone else do it. On small class C's people complained all the time so we have a 3 way valve with "take up" tube.

I hope to add a similar set up going forward on the trucks. Our small C's have an Anderson valve, which handles city water, tank fill and winterizing.

Roger that. Easy enough to work out a take up tube somewhere.

Going to resurrect this one as the time to do the deed is quickly approaching. Still haven't decided on exactly my route but wanted to get some more input:

1. Thinking about just using an external pump to pump outside through the city water hose. Pros are this will be super easy and also cover the hose and the filter enclosure. Con is I cant think of a way to get the hose to the pump or the pump winterized without filling the fresh tank.

2. Would be as mentioned above, but the act of getting 5 gal antifreeze under/near the bed is not one I'm crazy about. Thinking about either putting the valve under the W/D and dropping the tube to the wet bay or just running a hose down to the wet bay and put the valve there. Is there a layout that would allow me to use the city water hose coming up but add a valve before the pump (ie use the pump to pull city water)? I'm having trouble visualizing that schematic though.

I use an external water pump and 12v to run it. Suction hose side in pink gallon of antifreeze output side to rv water hose. I bypass filtration system before turning pump on. Also shut off ice maker/water in refrigerator line located under refrigerator. Bypass water heater and drain. Turn pump on open faucets, flush toilets, shower lines and so on.. till pink appears. Takes about 2 1/2 gallons. Done 30 min.
