Solar Options

While batting around ideas on expanding a portable solar set up, it occurred to me there may be other options like using the portable to expand roof mount. My wife is adamant about not putting solar on the roof, but we haven't discussed why. I think it is more the expenditure than anything else and what I have in mind may only be a little over $200.
I could put a couple of 100w panels on the roof of my fifth wheel, but not do the permanent wiring so that I would just connect when off grid. If off grid in the shade, I could connect the 100w portable for additional charging. I have a Solar30 controller on order which I plan to mount in the basement near the battery bank. The problem is connecting the roof panels to it when needed and how best to do that without flapping cables. I am not personally comfortable with drilling through the roof for cabling, but okay with the mounting part of it. I could run the cables off the roof and in through the landing gear area to Anderson connectors from the controller, but how to do a clean rooftop connection is where I could use some help. I haven't used MC4 connectors yet, so I don't know how easily they disconnect. I suppose SB50 connectors inside a junction box on the roof might work.
