I am new to this forum and this is my first post We are planning a trip for next year. One leg was to drive from Jasper to Banff via the Icefield Parkway. RV Life routing does NOT suggest this for our situation, a 35' fifth wheel towed with a 2017 Silverado 2500 gas truck. Wants us to go to Edmonton and Calgary to get there. Obviously this is adding many hours to the trip. So my question is, is our vehicle and trailer really too long or the hills too steep for us to take the Icefield Parkway? Has anyone does this with a 35'+ fifth wheel? Thank you.
