I'm curious what experienced teardroppers do to prep their trailer for winter travel? (Besides stay home because it's

As a Jeep owner in the Northeast I am familiar with the usual prep.
- Make sure the snow scraper and collapsible shovel are packed.
- Have a blanket, food, and water squirreled away in the trunk.
- Make sure the battery is still good, and charging properly.
- Make sure the tires have good tread and are properly inflated.
- Never let the gas tank get below 1/4 full.
- Drive cautiously in winter weather conditions, whether in 4WD or not (because lots of other people don't seem to notice that it is snowing out, or they think their AWD makes them invincible!)
- Speed up and slow down gradually, and take turns slowly.
What else is there to do specifically to prep a tiny travel trailer for winter travel?
How about any driving tips to avoid jack-knifing the trailer on ice?
Are their strategic differences for towing trailers that have their own brakes vs. those that don't?
Thanks for any and all thoughts!
