OK, I am new to this winter trailering stuff. Have an enclosed 2 place trailer, dual axle, aluminum trailer with brakes. I live on a steep hill, 2 miles down to the bottom with switch backs. Not always the best conditions, hard pack and ice often. Truck is old F250 4x4 with studs all around. (money spent on the 2 sleds and hauler

)
I do real well till the last 270 degree switchback that is way too tight even in the summer. The trailer wants to pass me on the inside as I get around it (slides down the inside of the turn and wants to jack knife, then it gets ugly).
So my question is will a set of chains on the one axle of the trailer do any good. It seems like it but before I spent the money I wanted some advice. If so which axle, front or back, both have breaks?
Oh, and I know , park it at the bottom, but that is not always an option - maintenance and such. Plus there is great riding up here.
I searche the site and found great tales of horror, but no solutions.
Thanks for the help.
