Depending on the road and what you want to see, it will vary from maybe 50 miles to 150 miles, rarely above that. Road construction can be very rough and long, with speeds at or below 5 MPH for mile after mile. If you go there with a timetable, then expect damage to your rig, because you will get in a hurry somewhere along the line. Go, enjoy, but remember, drive at a speed commensurate with the road conditions. I would guess that 90% of the RVs damaged in Canada and Alaska can trace the damage directly to excessive speed for the conditions.
