This will be an amazing trip UnConfused.
Seven years ago I rode from Toronto Ontario to Victoria BC, then down into the US. My wife rode on the back of my Honda ST1100 and after the first 3 days we didn't have any problem riding 400 - 500 miles a day. We went to the Road to the Sun in the National Glacier Park, North Cascade Hwy, Grand Coulee Dam, Buffalo Bill Dam, Yellowstone Park, Mt. Rushmore...8,000 miles in 28 days. Our last day we rode from Chicago to Toronto...We rode on dry pavement except for Banff in the Canadian Rockies where there was snow overnight that turned into heavy rain by the time we were ready to leave...(2nd week of August). Three days later in Spokane it was 100 degrees...During the course of the trip we stayed with relatives on the Canadian west coast and with "brothers" and we stopped to visit "worldly" friends in Chicago. The rest of the time we stayed at affordable motels. A few times we stopped at more luxurious Hotels to spoil ourselves a bit...it was a vacation after all.
If you ever plan a trip my way just let me know and you can stay with us...and we may right together for part of the way.
