My rig came pre-wired with a connection on the roof. Without doing the math, I have less than $300 in two 100 watt Rich Solar panels, and a 40 amp MPPT charge controller... I replaced the wimpy 10 amp controller that came with the rig. The bonus is you can also use that controller when you switch to lithium... just tell the controller what type batteries you have, and it knows how to cycle for them to keep them "healthy".
YouTube is your friend... many detailed install videos. I'm in Ohio, and the two panels keep my batteries constantly at 13.6 volts. The MPPT controller has a benefit over a simpler PWM controller in that it occasionally cycles to bulk charging at 14+ volts to help prevent sulfation of the battery plates.
Honestly this was one on the easiest RV projects I've ever done. And worth every penny... I NEVER have dead batteries anymore... and don't even think about it much.
