Re: [RC] Snow chains on trailers? - Sisu West Ranch

High country hunter friends of mine claim that you need to put chains on all 4 corners of both the truck and the trailer.

Remember that they are talking about gravel, unmaintained mountain roads which often are banked completely the wrong way.

On the other hand, on the way back from Phoenix we went over Morida Pass on I-15 between ID and Dillon MT. The pass was snow packed etc. and we had a 4x4 with summer tires. We just put it into 4 wd and went slowly. Now the highway department did not have "chains only" signs out, the pass has a rather gentle slope with no real switchbacks. We only saw 2 cars in the ditch, and only one had serious injuries associated with it.

I suspect that going around switchbacks on the downhill would be the real test. We did not want to take that test so we decided not to go over Lost Trail Pass, but to follow I90 to Missoula. Lost Trail pass has some switchbacks signed for 20 mph. That is for dry pavement. The detour added 122 miles to the trip, but was better than unsuccessfully attempting a pass.

Another thing to consider is how much snow/ice driving experience do you have with and without trailer? I guarantee if you drive a rig on snow/ice you will eventually loose traction and skid. All of the advice about "stearing into the skid..." won't help without experience. Experience is the only thing that allows you to feel a skid and feel how much correction to make for the initial skid and to the resulting counter skid etc. It is sort of like knowing which diagonal you are on and which diagonal you should be on without looking and thinking.
