Really like your Burb. Are your running boards custom made? They look beefier than the stock ones. I have been looking for and not finding some kind of step/rock rail/slider to protect the rockers. Also being on dirt every day, it would help to keep dirt/mud off the sides of the truck. If those are n0t stock, how do they attach to the frame or body?
You may very well know more about solar than I do... we just started experimenting with the harbor freight kit this past summer to try to understand how it all works. On your solar set up consider parking out of the shade, and providing a more flat panel direction toward the sky. The panel needs the most unobstructed sun for the longest period of the day possible.
