Solar suggestions

I am about to pull the trigger on some panels and controller. I have around $600 dollars to spend. I should have my maggie rack installed next week which I am going to use to mount the panels to the roof of my 2011 Northstar truck camper. Currently I am thinking about going with g**** solar 100 Watt panels. I think I can fit 3 panels on the roof. For the controller I was also thinking about the ecoworthy mppt. Does this sound like a good combination?How should I wire the 3 panels? series or parallel ? Another option is going with two panels on the roof and one 100 watt g**** solar bendable panel that I can move around so it's always in the sun if I am parked in the shade, I could add a cheap PMW type controller for that.
How does this set up sound?

Forgot to add that I have what looks like 10 gauge wiring from the fridge vent to the batteries ready from the factory.
