I did upgrade the controller I believe, can't remember now. (edit, just looked, no I took the default controller, i can upgrade later)
I'm working with a popup camper, and might not even mount this to the roof. (for now anyways) I'll just stick the panel in the camper while traveling and then set it up once camped.
Thanks for the other information, sealant and offer of the camera. I'm not sure what I'll do, since working with the popup, I have multiple points of entry into the camper without hitting lines and such, especially if I don't go through the roof. I was originally going to get the boat rack for the top of the camper and then use that as the mounting point of the panel(s). I'm getting on a short time frame and might not have time to get all the things done I want for now.
