Taking the toy hauler up to the ski resort? Any problems?

Carry chains for the truck and trailer. Both are required when the signs are up. I like to use the spider bungees too (Les Schabs carries them) because tight chains let you drive faster without causing damage.

I don't brake any different in the snow than on pavement other than allowing more distance. I'm not sure using the trailer brakes alone is a good idea since you're lessening your braking power and number of wheels with traction, plus your trailer doesn't have ABS.
