If the OP comes in from the east, on the Indiana Toll Road, they could leave at the Chesterton/Valparaiso Exit and it's 7 miles north to Indiana Dunes State Park.

The OP is coming in from Maryland, presumably on the Indiana toll road. Staying in northern Indiana would mean they avoid the nasty traffic west of the Gary/Hammond area. Indiana Dunes is a great place and close to the South Shore to get into downtown Chicago, but it's not the only campground in the area if there are no sites available, or full hookups are desired.
