I have a Zamp inlet on the side of my RV. We don't dry camp often but I'd like something to help us make it through the weekend when we do. Mainly using fridge on propane, minimal lights, water pump, and possibly some charging via 12v cigarette port. In this use case, we typically make it almost 2 days. I just want something to keep the battery going for another day or so. Here is what I came up with:

Am I missing something? The adapter will allow the charge controller to plug in to the Zamp outlet. The charge controller will be mounted to the back of the panel and connect to it. I've read that it's better to have the charge controller closer to the battery but due to the location of the Zamp port I don't think that's an option for me (not wanting to rewire since it is a minimal use case). Am I missing a connection somewhere? Trying to wrap my head around how and where everything will plug in. Any advice is appreciated!
Also saw the Harbor Freight 100w kit and was wondering if that would work in my scenario? What other parts would I need? Thanks again!
It doesn't sound like you will have a hard time coming up with enough chargability with a portable solar or two. Something I didn't see was the configuration, condition and age of your battery bank. You can have a nice solar charge setup but if your bank is weak you won't make it three days. Also,I attached a link(you'll have to copy and paste it)that gives you everything you need to make a real nice portable 200w setup with a parts list, prices, links and instructions.
