Yes it is wired for a 2nd above the kid's bunkhouse in the rear. Just never noticed it as much before since our last big trip we were getting to places later in the day and usually had some sort of shade. Sitting in the open sun for three days straight really pointed out the need. It's funny, because our salesman was obviously focused more on making a sale than upselling options. I remember asking him specifically if a 2nd unit was a necessity, and he told me not absolutely unless I loved to Florida or something. We had a good laugh. Then I moved to Florida.
