Hi Peter,
I agree with C Gypsy, Comox has a good boat ramp and easy parking for truck and trailer. During summer there will be several rigs parked overnight. I have never heard of any security concerns. I think the cost for launching and over nighters is a bit less than Gypsy mentioned. But it is not cost prohibitive if you are parking up for just a few nights.
Unfortunately I do not have a driveway you can use since we sold the big house. Stay in touch on dates, maybe we'll cross over together.
Martin.
