Today I installed two 160 watt solar panels and a PWM charge controller on a 2014 Thor Miramar 34.2 Class A motorhome. The best part of this job was the excellent surf rolling in. The San Elijo State Beach Campground is near Cardiff by the Sea and many of the spots are on a bluff overlooking the Pacific Ocean. You can run your generator but only during the day. There is no power at these sites so having a solar system to keep the batteries charged is the only way to go.
