Scott's valley rv. They'll do the solar with no issues. I imagine a moderate redesign is in their wheelhouse as well. Sounds like 1der has you covered as well.
I highly recommend 1der. I bought my Fiamma awning from him. He came to my home and installed the awning a few days ago. He had to do some modifications to my hightop to make the awning brackets fit. He did a great job on the installation and its professionally done. I'm very pleased with his work, customer service, knowledge etc. Very easy to work with.
