Colorado Ski/Camping trip coming up

hey y'all,

I'm driving up to Colorado from Louisiana to go ski with a friend over Mardi Gras week (end of February). We will be in the Arapaho Basin/Keystone/Winter Park areas. We haven't made up our minds. We are looking to camp out at night instead of staying at a hotel. Can anyone give me tip on a great place to camp with my truck? Not looking to do much off-roading, just a nice place to set up the tents in the afternoon. Both of use have the equipment and experience to do this safely.

Thanks--
Eric
