The good news is it was clean water. The bad news is even clean water gets into everything and can eventually cause mold and rot problems. I'd probably file the insurance claim and let them hire some pros to go in and make sure everything gets dried out. Also filing a claim protects you against future damage that may be found related to the water.
Although I assume you have no learned this, I never leave the water on when I leave my motorhome. I try not to even leave the water pump on if I remember. In this case a faucet got left on, but RV plumbing can easily break when left under pressure.
