Final report: I checked all tires, carried chains, loaded smart. Left on the 2nd and had sun and dry roads all the way to Roseburg. There had been early morning ice on roads but I left way after that. Biggest problem the first day was the sun in my eyes (its so low in the sky this time of year that it was always on the windshield.)
Day 2: still bare and dry roads. That was never a problem. Saw lots of snow piled up from plows from about Ashland to Shasta, but none on the road, no ice, either. But I did run into a problem on Day 2- my tail lights
quit working. Not the signals, which I'd messed with before I left, but the running lights
. Both sides (don't they go back as one wire? Which one?)
To solve that I did all the night driving with the hazard lights
blinking so that I'd at least be visible. That seemed to work just fine as far as traffic went, but it was a pain in the neck in the car as those things blink audibly. But it worked. If those had also stopped working I'd have had to stop somewhere so I'm glad I thought of the hazard lights
Subaru towed the trailer just fine, no sway, and handled the hills fine (once an awhile in 3rd, usually in 4th) and the downgrades (in 4th). I got about 16 mpg towing from Central Point to Red Bluff, and 20 from there to Fresno (no more hills.)
Got home and had to do some fast loading and unloading- I hadn't left both sides of the garage clear so had to put the trailer in my garage, then unload the Thule box and remove it so that the car would fit my neighbor's garage (height only 6 1/2 feet, old door on old building.) So today's first big job is clearing room in my own garage for my car. Eventually I'll have to trade spots as the "trailer side" is longer (a stairwell takes space on the car side) and I need the extra space to work on the trailer.
Thanks to everyone who offered advice. I'm glad I was aware of potential problems, and had looked up the info on how to use chains on the Subaru. I'm more glad that I didn't need the info!
Saw quite a few fifth wheels and a few travel trailers, plus some utility trailers. I think a lot of people took advantage of the dry weather as I did.
