Dump/Fill -- Columbia Icefield Visitor Center -- Camping

Before you pull into Wilcox with your rig, you might want to scout with your truck -- not sure about the access to the dump station. I am pretty sure the campsites themselves at Wilcox are too small for your rig, and the interior road is very tight.

If you can fit in there, it is a very nice campground -- quieter than the parking area at the Icefields. There are several days' worth of good hikes in that vicinity.
