Crundwell, 59, is accused of misappropriating more than $53 million since 1990 from the small town to help support a lavish lifestyle and her nationally-renowned horse breeding program. The RV is being auctioned off by the U.S. Marshals service.
Four hundred of her horses will be sold by September 30, according to prosecutors.
The developments came up during a hearing where Crundwell's defense attorneys requested more time to review the 18,000 pages of evidence.
If Crundwell is found guilty, net proceeds of the sales will go toward restitution for the town. Crundwell pleaded not guilty to wire fraud.
