Kinda pricy but 100w will probably be enough considering your low usage, the LEDs and the 6v batteries for a weekend.
Mixed reviews
I am concerned about the controller being in the kit. My panels can put off some serious heat even after a short time in the sun. I'm not talking the kind of heat a little fan can dissipate either. My controller has a temp sensor like the kit too. When it gets hot, it clips the amps by more than half.
as a kit, if the controller dies is the kit toast?
15 feet isn't much cord. I have 25 ft and that's shorter than you think when trying to avoid the shadows of the trailer and awning. Also my 25 ft of cords is on the panel to controller side, not the controller to battery side. The longer the run from the controller to the batter, the bigger those wires need to be.
Those would be initial concerns but that said if it functions, it would probably do well for you. Personally I'd look for the components separately and get more for less money. It took minutes to tighten the screws on the controller for the battery and panel leads but now my set up is near as plug and play as the kit. Put the clamps on the battery and click the panel cords to their connectors and I'm done.
