FYI, there is not that much of a spread between the latest PV technology and ancient (five years previous). Not much that matters for the size and application of an RV system.
I use a single 235W polycrystaline module and a Morningstar MPPT-15 controller. If you can get by with that level of harvesting, the Morningstar has a PC interface so there is a big string of data available and any combination of charge setpoints or durations. It also has battery temp compensation. The included MSview software is kind of clunky, IMO, but is fairly full-featured. You can store historical data and graphs as well as real time.
As others have noted, don't plan on a discharge of 80% with AGM's. You will severely reduce the service life.
