Aaron, good luck on your tour. I don't really have any words of wisdom or advice for tents/supplies/whatnot. I just thought I'd say that I tend to find the drive to Jasper pretty boring up until Hinton. Would it be an option for you to hang a left at Jasper and continue to Banff and Calgary instead of turning around? Could a friend or relative pick you up in Calgary? I think the Icefields Parkway would be a much more scenic tour than just to Jasper and back. Another option would be to go south from Jasper to the Saskatchewan River Crossing, then east on Highway 11 to Rocky Mountain House, then north on Highway 22 towards Drayton Valley. From there, there's a few options for getting back to Edmonton. Again, it's definitely a longer route than to Jasper and back, but I think it's nicer scenery.
