I tow in the snow all the time. Well not as much as I’d like to. 32’ enclosed snomachine trailer. Now it’s not as heavy as a TT and w 4wd and siped mud tires, I’ve never used chains on a highway or paved road on the truck or trailer. They only come out on icy hills or in real bad spots.
Personally I would not want to tow and chain up a 2wd unless absolutely necessary.
Marginal traction you may need to just chain the drive axle.
Poor traction, all 4 plus one of the trailer axles.
Once you have chains on, you’re going slow enough to handle just about whatever is hooked up.
And as mentioned. Warm, wet greasy coastal concrete is way worse than champagne powder. And everything else is in between.
