Crate & Barrel has this cute colorful doormat from Chilewich:
We use these Chilewich mats inside the Airstream (from Chiasso in Metallic): one at the door, and a larger one (purchased directly from Chilewich) in the kitchen. They're great, and when they get dirty you can just hose 'em off and let them dry and they're good as new.
