I get the idea you are planing to leave the rig in the lower-mainland and "day trip" to the island.
I really question this idea, If you were to take the 8AM boat you need to be to the ferry terminal by 7:30 (with reservations) and wouldn't be in Victoria until ~10:30AM.
If a similar statement about the return.
Of course there is the INSANE expense of paying to take the rig across the ferry. Which is why for our trip next month (Sept) we are leaving the rig behind and staying at a Motel.

When someone tells you to buy the same rig they own, listen, they might be right. When they tell you to buy a different rig then they own, really pay attention, they probably know something you don't.
