Sorry can’t advise you on what your looking for but...
Come October you can expect weather going over the Canadian passes maybe even down to valley but no need for any concerns looking at the roads historically. I do remember a time tho when the end of August snow was no surprise and plenty more of it. By November you had to watch for openings in the piled up snowbanks to exit.
I’m a big fan of tire chains. Not likely you will be using them on the highways but in the case you slide sideways out of your sleep spot and discover a timber wolf or grizzly in the shadows watching your troubles then they can come in handy. Even for a slippery spot you can just toss your open chain under the spinning tire.
Expect cool nights, everyone aboard should have a toque.
Stock up on bear spray, air horn, oils antifreeze and wiper fluid jug after jug. The further way north you get into Canada things become more expensive…unless you have discovered a different route.
Octobers the best time to drive up in my opinion. With the tourists gone home red plaid shirts are at discount, wildlife is on the prowl and the northern lights will be in full display out your windshield well before arriving in Alaska.
Enjoy British Columbia on the way!
