I didn’t read all of the posts...so this may be redundant! Cables for truck, and check for fit. AND MOST IMPORTANT.....cables for trailer (also checked for fit)!!! If, you need to cable/chain up the tow vehicle....you need to do the same for the trailer. IF the truck stops faster than the trailer.... it makes for a really good “Kodak Moment”!
Living in Wyoming and “not” ceasing to enjoy rv’ing in the winter....we “ALWAYS” keep cables stored in the 5er. When you live here, it can/and does snow at any time. We’ve been in snow in every month....except August.
Downhills will be your biggest (other than an emergency stop) challenge. Again...this is why you “cable” the trailer and get comfortable with manually using your brake controller. Using the controller ( not overly aggressive) will help keep everything “in a straight line”!
On the subject of grades... I would recommend testing the rig, cabled-up, on a flat section of snow-covered road... before getting into the hills. This will give you some knowledge of your trailer stopping ability! If it doesn’t stop adequately OR you do not feel comfortable... you should wait out the road clearing.
We’ve got a Christmas trip planned in our little class c....snow in the forecast! It’s not 4 wheel drive....but I have cables for “both ends”! This will be our first winter outing in it, and I’m a little apprehensive. So.... I’ll be following some of the advice that I gave you!
However, your biggest concern....should probably be “the other guy”!
