I got the "Jumbo Panel Kit" from rvsolarelectric.com, it includes a controller and 20 Ft. of cable which turned out to be just right for a 2720SL.

The cable runs along the back edge of the top shell, down the arm and attached with zip ties to other electrical cables that are factory installed and then underneath. The 2720SL has a small plastic box built around what I think is the tub drain. I've got the cable going into the TM there. This space goes right into the back area where the battery is located. I placed the controller on the wood wall right next to battery. We've had it a year this month, and is still working fine.

I can email you some picture if you are interested. It's really was much simpler than I ever imagined. Just takes a little patience/planning, definitely NOT rocket science.
