Oil leaking rear wheel area

Over the winter I've noticed oil leaking between the rear wheel cover and the tire. I've seen what's involved with the front bearing and gasket replacement but wasn't sure what goes on in the rear hubs and what's the scope of work

Your chassis , has " full floating " rear axles. Meaning the wheel bearings are running in diff fluid, on races in a hub assembly, the axle has no contact with the bearings and drives the hub through, 8 bolts that hold the axle to the hub. There is a flange gasket between the axle and the hub, and if that's what is leaking it's an easy ; but slightly messy; fix.
Do you have stainless wheel covers , or alloy wheels?
If stainless covers , remove the covers and try to isolate the leak, may be obvious as soon as the covers are off, may require a clean up and drive the coach to pin point the leak.
If it is not the flange gasket leaking, and removal of the tires and hub is required, JMHO, that is not a DIY back yard job.

The axle is very easy to remove so that you can replace the gasket. Before you start jack up the side that the leak is on. I would raise it 3 or 4 inches so that when you pull the axle, you won't lose very much of the oil.
