I would leave something on when it is plugged in all the time.
Fridge or something.
Yes, get the IOTA smart controller, assuming you still have the converter that Warrior put in originally.
For the roof, the front and rear seams, I would use Eternabond tape. Amazing stuff and won't crack like Dicor will over time.
I did that to both of my front and rear caps. 5 years and still looks great.
