Hey Carol welcome aboard.
Ok nice class C. IMO adding solar for your needs should be really easy to do with a 200 watt portable suitcase solar panel. I actually covered this in a video we did about 8 months ago.
In Part 2 of this 3 part series I covered:
• What we did to the battery bay, portable solar, propane, generator, under the chassis and a couple of other things
If you're interested, go here and see how this solar set up works. It's super easy and will provide what you'll need.
Good luck to ya.
