Headed North in Winter (Eastern Washington)

I am installing a 50 amp line in my daughters home when I arrive. I'm staying In the trailer for the three weeks on her property in Pasco, In the southeast corner of the state. Water as I need it.

Since Pasco's on the Columbia, it's a little more temperate than some other parts of Eastern Washington. Wind might be your biggest concern- if you can park the rig on the lee side of a building you'll go a long way towards keeping things "warm". Or at least what passes for warm in South Central Washington that time of year!

Temporary skirting of some kind is a good idea, but since this is short term: With a 50 amp hookup you should be able to run enough space heat to protect the plumbing, especially if you're using your furnace for room heat. I'd recommend periodic filling of onboard water tank rather than a live hookup, but if you do use one, heat tape or some other protection will be prudent.

Per your route north: There's really no necessity to travel Oregon's high desert (Baker City etc.) at all to get to Pasco from SoCal.

If you want to avoid the mountains/desert altogether, think about taking Hwy 101 through Oregon and turning East up the Columbia at/near Astoria. This would make most of the trip practically at sea level. The Gorge is windy, especially on the Oregon side...Washington 14 is my usual choice for making that trip. Two lane hwy, but far enough away from the river in most places to be sheltered somewhat from the howling winter gale that often sweeps downriver along I-84 in Oregon.
