....A couple of additional thoughts....
My solar controller (and most other RV sized controllers) are rated for 30 amps.....so perhaps having the alternator (130A) or my Progressive dynamics 60A charger connected to the controller may be too much....
There are certainly larger sized solar controllers that are rated for higher amperage for cabins, etc...thinking of some of Midnite Solar's offerings.

However, setting aside an all-in-one solution for a minute, if the shore power smart chargers and/or alternators tend to undercharge on float, even with our present setups whenever the sun is shining the batteries should be topped up with the smarts of the solar controller, so is the added smarts from the alternator or shore power really that meaningful?
I've had some thoughts on cable sizing ...this thread is probably a good place to talk about them as well.....
We regularly talk about proper wire sizes for charging the batteries from solar, shore power, alternator, etc.......if the conductors happen to be undersized, by the time the battery gets charged enough to be in float charge mode, the current required is tiny.....so why big cables??
...I suppose that the voltage drop due to undersized conductors in bulk charging may have some effect but I'm not sure what that is....perhaps charging time.....again, as the battery charges, it's drawing less current all the way to float where it's drawing a mouse-fart's worth of current....
...the above thoughts are considering slightly undersized conductors...not about using lamp cord to charge batteries.
