I doubt you really need chains esp if you have awd. Are your stock tires m + s ? I know in British Columbia for example, m + s (mud and snow) tires are required which are standard on Canadian crvs, otherwise snow tires until March 31. Maybe you need to carry chains but I doubt you will need to chain up. Anyway if you are 2wd with the standard tires, you could carry the chains (I would be tempted to go with cable chains) Don’t install until absolutely necessary but do install a couple times so you know you can quickly install.
Let us know what you did and how the trip went.
