Actually, I'll throw this one out for free since I can't claim it; I learned about it last year from my bud Louise. Call up or email Aaron, the race director, and tell him you're available to drive one of the RVs from Calgary to the start town. Simple as that. Well, the paperwork takes a little while. Make sure you get detailed directions or a map as you might need it. I was supposed to follow Eric & Lou to Fernie, but my paperwork was taking too long so I ended up going it alone. I'm fairly decent with directions, but I got lost. I eventually picked up a hitchhiker as a navigator. It was a fair trade, directions for a ride and I got plenty of good stories about the places along the way.
If you have the luxury package I'd be surprised if you can't pick up your RV (like the one below) immediately so you can pack it full before the race.
Everything in this baby started to shake really bad when I got it up to 95
I just realized that you probably don't have access to Aaron so an email to the Transrockies "info" address is the next best thing.
