Be aware that whatever is on your carrier will be covered with whatever you've been driving over.
Pay attention to this ... it is dead right. I would not want to haul a deer on one very far on a dusty road. If you're hauling soft luggage, look into one of the heavy duty dry bags used for rafting. The roll up / seal does a pretty good job of keeping the worst of the dust out. Zippered closures don't work all that well. Ice chests seem to flex and breath going over bumps and will sometimes suck in dust as well.
