We're planning a 3 weeks long trip this summer from Manitoba to Vancouver Island. We'll be driving all the way. I'v driven to Edmonton before, and my partner has driven as far as the Okonogan Valley. He is comfortable driving through the mountains but says it will be a lot slower, as we will also be pulling a tent trailer. Can anyone who has done this on a regular basis, (or at least more than once) tell me how MUCH longer this could be? I calculated that from Canmore AB (where we will be stopping to see relatives) to Kamloops BC it is about 351.51 km as the crow flies. I'm figuring that through the mountains we may be only driving about 80 km so it could take us 4-5 hours to get this distance. Am I close?
