I agree. In fact, I think you're one of the few posts asking for advice on "my dream" who I think actually has a great chance for success at it.
You might take your son camping at a hosted campground and ask the host if you and your son could shadow him/her for a day. Then you could see what the tasks involve, how your son reacts to certain tasks, etc. Then, back home, you can find ways for your son to practice those tasks best suited for him. For example, you could start having him switch out the TP in your bathroom at home, or using a pick-up tool to pick up garbage, so it is a familiar habit when you start hosting.
