Any comments on weather and road conditions on I15 through Montana, Idaho and Utah in late January and February? I'll be towing a 5th wheel with a 2500 HD 4x4 and have chains available.
We regularly travel through BC to Vancouver any month of the year and periodically experience short term road closures of the Coquihalla, Ok connector and Rogers pass. Generally, the problems occur at elevations above 4500'. But the distances of those elevations are only 100-200 Km.
I used Google Earth to track the elevation from Helena Mt to St. George Ut. along hwy I15. It appears to be consistently above 5200' and frequently above 6400' for very very long distances.
Is this a trip that can USUALLY be made without significant delays, trauma and white knuckle events?
Please share any experiences.
