If the description of your rig says you have a 26 foot rig, try Kala Loch(pronounced clay lock) campground. You might have to find a separate spot for the truck as the sites are in general small. It is a great base of ops for the west side.
North a bit is Palms where the latest vampire series was shot.
Just north nd I mean just north of the Kala Loch campground is a jasper collecting are. There areocean tumbled pigeon blood specimens to be found after high tides and storms.
Thar's all off hand, DW might add some stuff later.
I forgot about a St Pk to the west of Pt Angelus. Vest nice and quiet if available. I'll ask DW the name.
