Large sites around banff?

Hey, we are new to the site and looking for some info. We have a large 2009 trail light 32bh. I used to camp with my parents at two jack in banff. And I miss that kind of camp ground. We've had a seasonal site at the I laws land for the last 5 years or so but now are looking to get back to the mountains.

We rent looking for a open trailer court type of campground with hook ups. Looking more so for some where that will accord ate our size trailer that's relatively close to banff where we can dry camp with the kids and dogs any input would be greatly appreciated
