I used the included wiring, but spliced into it and put the controller in the basement MUCH closer to the batteries than in the hallway of the camper where Jayco wants you to install it. You want the charge controller as close to the batteries as you can. The run from the panels is higher voltage, so not as much of a concern.
I was able to get 2 100 Watt panels for $90 a piece, and did a PWM controller. Not as much $$$ as the MPPT, and I may lose a little efficiency in certain circumstances, but it works well.8 gauge from the roof to the controller, and the same for the 4 feet to the batteries. I also have a 100 watt portable on 8 gauge wire. (We sometimes park where the RV is in the shade, and the portable gets me 4-5 amps of charge when the roof is shaded.) 300 watts total.
Whole system cost around $500 by installing myself and catching the panels and controller on sales. (Renogy did a great Black Friday sale on the portable panel with the Adventurer controller and 40' of 8 gauge wire.)
