This is not a RV application but there seems to be a lot of solar knowledge on here so I thought I would ask. I run a 12V system in my remote cabin for LED lights and RV size water pump and CD play...
For just a battery maintainer you can use a low wattage panel and it does not have to be on the cabin roof in the shade. I have seen such cabins with the panel up a tree nearby where the tree-top is in the sun. You can use really long wire and it won't matter for this low amperage job.
