As I read it, the OP is referring to the PORCH light being dim.
My small gem of knowledge learned by experience.....don't pack the trailer frig or freezer full to the brim. It needs air circulation to work effectively. I had the great idea on a longer trip a few years ago to try to get 1 full weeks worth of food in the frig and freezer so we didn't have to think about shopping until we were at our longest stop. Bad idea. We thought we had a problem since nothing seemed as cold as it should.....until we started working through the mass of food and problem resolved itself. Even with just 2 of us, I don't pack more than about 4 - 5 days MAX, usually more like 4. If you have more in your family, you may have to shop more often depending on the bulkiness of what you're getting. Happy Camping!
