I'm not sure how you're going to drive I-15 from California to Washington, maybe you mean I-5. You'll have to go over the mountains in northern California on I-5. I'd be a bit concerned after reading the owner's manual for your 2019 Subie.
Here's one quote: SUBARU warranties do not apply to
vehicle damage or malfunction caused by
trailer towing.
Here's another quote that isn't encouraging: When towing a trailer on a long uphill grade continuously for over 5 miles (8 km) with an outside temperature of 104F (40C) or above Maximum total trailer weight 1,350 lbs (612 kg)
Subaru is telling you up front that their vehicle is so marginal as a tow vehicle that they won't warranty any damage that may result.
