[Closed] RVing Canada

Hi has anyone any expierience of RVing in Canada.
Me and Mrs Bh are off in June for 3 weeks around BC and into jasper, Banff, Canmore etc.
We are wanting to rent an RV, probably a 20 or 24. We'll be starting from Vancouver and going straight to Van island, is it worth getting the RV for this part of the trip?.
What is the most cost effective method of renting one, from a Van company orare some of the out of town ones cheaper? Will the out of town one deliver to van? Any recommendations of who to use?
Thanks for any help!
