Check out the "electrical, charging system, and solar" sub-forum under General Tech and Repair. There are many different threads on going solar. Also, check out the website for AM Solar. There are a lot of educational items on that site.
I have a feeling if you let Camping World install some solar components it will be a waste of money. Live in your trailer, as is for now, if possible. Learn the ins and outs of travel trailers before upgrading to solar power. If needed, get a generator first. There isn't as much of a learning curve with those.
