Congratulations on your Trillium 1300 right? Looks like the 13 foot model. What year is it? I bought my 1978 Trillium 4500 Deluxe 3 1/2 years ago and love it. Can' nt wait for the day to get my family up to Baniff, I heard it's like a slice of heaven!! Dave in Michigan
Banff is lovely, we live about a 5 hr drive from it. June and September have less crowds but you might still encounter cool weather. I always feel bad when you see the tour buses full of people who have come half way around the world to see the Rockies and the mountains are hiding in the clouds - so give yourself time if you have to wait out the weather. The Icefields Parkway is a great 1 day drive between Banff and Jasper too.
While you are up in this neck of the woods, check out the Okanagan and Shuswap (lakes area) for some warmer weather and swimming etc. The Okanagan also has great wineries. If you plan a trip to BC too, check out the BC Gov't Parks website to help plan your camping stops:

Since we've got our Trillium I'm on there a lot planning our summer!.......Jo
