There are just a couple of parts needed for solar installation.
1. Solar Panel(s) with mounting hardware
2. Wiring from the roof to an area close to your House Batteries
3. A Solar Charge Controller to connect the panels to and then to wire from the controller to your batteries
That's all you need. There are probably thousands of websites and hundreds of YouTube channels on this type of install if you are doing the work yourself.
As per usual Amazon can sell you everything you need individually or in a "kit" form. But you should do some research and learn about all the different items and brands to make an informed decision before ordering.

If you want to pay to have a system installed there are a number of residential solar installers near you in Durango - but for RV specific installers you may have to travel to the Phoenix area. Though many independent RV techs can do this work too.
