I did live in Forks for awhile years ago but now live on the east side of the Peninsula. I still camp near there several times a year, though.
As a fellow West Coasterner (no sticky climate like the East has), it occurs to me to ask whether you intend to keep/use the A/C? Depending on camping style, it can be excess baggage since use depends on available power.
And you're blessed with perhaps the best ventilated fiberglass trailer ever made...jalousie windows on all four sides and at least one roof vent. Including the window in my door, there are SEVEN openers in my trailer walls, eight if counting the escape
window. It's really remarkable how much air one can get moving by way of the cross venting this allows.
I boondock almost exclusively all up and down the West Coast including some pretty hot inland areas and have never suffered by way of the lack of an A/C unit.
