If coming up from Montana you might consider:
1. Stop in Waterton for a couple of days. If you have a Toad drive up to Red Rock canyon. Visit info centre for other walks.
2, Stop in Cardston at the Reynold's museum. (Day trip from Waterton.)
3. Visit Head Smashed in Buffalo Jump off Hwy 3. Look on-line for camping spot here.
4. Take Hwy 40 into Peter Lougheed park, stay a couple of days. Lots of walks here.
5. Move to Banff, Tunel mtn. for 2-3 days. Crazy busy town but some like it. The Sulphur mtn Gondola is worth while here as is the Whyte museum.
6. Move to Lake Louise for 4 nights. Do walks at Lake Louise, Morraine lake, see info. centre (good one), allow a day to Visit Field and drive up to Takkakaw falls (toads only here).
7. Move up the Icefields Parkway--lots of pull-offs and beauty spots like Bow lake, Peyto viewpoint. You could likely fit the rigs at Waterfowl lakes (unserviced) or at the overflow camping at the Icefields (unserviced, parking lot, but lots of room). Visit the info. centre here. Nice hike to Wilcox pass, but uphill. Icefield snow coach ride is pricey but worth it. The glass viewing platform north of the Icefields is NOT worth it as you see the same things from the highway.
8. Move to Jasper (Whistlers campground) for 3 or 4 nights. Drive toads to Edith Cavell and walk here. See info. centre for other walks. Another Gondola here to a low peak (Whistler's) if you wish.
9. Move West to Mount Robson provincial park for a couple of nights. Info centre here for advice on activities. Take Hwy 5 West but this is out of my area so someone else can advise you better.
Do try to get to Drumheller as the museum there is world class. Don't know where you would fit it in as it is North and East of Calgary a fair distance. There are RV places to camp. There is so much to see at the museum it takes us two days.
Hope this helps. Do book serviced campgrounds ahead and do check out the distances involved.
