Spokane to Calgary with heavy load - best way?

Please don't bring your under powered / over loaded vehicle into my Province and endangering my life as well as the rest of the people on the hiways
Over loaded vehicles crash and people die every year in these mountains because of what your planing on doing.
We also get people that are not used to mountain driving going to fast and crashing because the corners come up to fast.
Please don't drive the vehicle is the condition you posted, my life may depend on it.
