These might also be of interest Kevin - it's a system called PillowTrack
Effectively, a set of 2 rugged rubber bags that are grippy and either fill a space or give you traction if you get stuck.
Might be worth double checking the burst pressure first as you'll be fully loaded for the trip.

I've heard they're not overly popular from guys on the forum but they look more versatile than those big sand boards to me, hence my post.
They're not cheap @£145 but there's an offer button. I might get a set but if we have to use them, it means we picked the wrong route on the trip. You'll probably hit more mud than us on the West coast so maybe you'll need recovery kit more than me.
I can see them being more useful for offroad playing where getting stuck isn't an issue.. Then again, you'll probably have someone to pull you out anyway and the cruisers don't get stuck do they
