Be sure to check YouTube for installation ideas. I did, after posting the above, and it kind of whet my appetite for adding these lights. I generally don't like a bunch of extra light around my campsite, but if we come back to camp on a dark night, the little porch lite is kind of useless (it's yellow to discourage bugs), and some extra LED might be welcome. I would be sure to mount them so that they would illuminate the ground while the awning is closed, because we don't use the awning much, and we definitely don't use it while away from camp.
Since you don't have a porch light, I don't see any problem connecting to any 12v source in your fridge compartment. You can also get strip light kits that come with a 120v dongle, so you can connect to an AC outlet if that is more convenient, or plug it into an outside GFCI outlet if you have one of those. Some kits come with remote controls, to turn them on/off, and various light shows and color changes, if that's your thing.
It might also be easy enough to fish a wire across the ceiling to a ceiling light or fan fixture. Don't sweat drilling a small hole through the skin. Just put the hole right below the awning rail, keep it as small as possible, and fill with Dicor after it is all wired up. There isn't any reason to worry about leaks if you do it correctly.
