You can find jobs that are not physically demanding. Some camp host positions involve more riding around on golf carts and sitting out front of your RV being social than they do walking. You might find an office job that doesn't require a lot of standing. Perhaps something like a ticket taker at an attraction. You may also be able to be a greeter at a retail store. These are just a few I'm thinking of right off the top of my head. There are others.
