We had a Bigfoot 10.6 and liked it a lot. I have also read many positive things about the NL. Both are similar clamshell construction.
I can't tell if you mean it only has one battery or only fits one battery. Our BF held 2 easily. Things like TV and solar can be added. I would base my decision on which camper you like more and not worry about a tv or a solar panel.
Our Bigfoot did not have a full queen bed, one of the gripes I had with it. At 6'-2" I couldn't lay flat without feet hanging over. Also couldn't find sheets to fit properly.
