Authorities in Mississippi say a RV drifting into other lanes and onto the shoulder was stopped and 11 kilos of cocaine were found during a search.
The Sun Herald reports 69-year-old Victor Wendell was arrested April 12 and is being held with no bond on suspicion of drug-trafficking.
A federal magistrate judge ordered the complaint turned over to a federal grand jury on Monday.
A federal complaint says Wendell's destination was an RV park in Jackson County, where he'd planned to get a campsite and wait for someone to contact him about arrangements to sell the cocaine for cash.
Federal agents said Wendell has admitted it was his second trip to Mississippi and said the plan was to return the cash to McAllen, Texas.
Online jail records did not list an attorney for him.
