Need Renogy Installer SoCal Ventura Familiar with Airstreams

Hi I need a recommendation for a installer in the SoCal or Ventura area who is familiar with Airstream Trailers. I purchased a trailer where the previous owner installed this unit and need to have someone check that its working properly and clean up some wiring. It needs to be someone who has worked on Airstream Travel Trailers as you cannot stop around on the roof of these trailers like other brands.
Thank You
