Brake Drum Removal

I have a 1999 Fleetwood Jamboree Motorhome on a 1998 Ford E-350 Chassis With A V-10 Engine With About 85K Miles.

It has dual rear wheels. I want to check the rear brake shoes as I think that they need replaced. After examination I am fairly sure that the axle needs to be removed so the drum can come off. I have removed the axle. It appears that I need a special tool in order to remove the drum bearing. Please advise.
