On the otherside your controller does have a 2 amp aux battery charge output, I would probably hook it to starter side of the surepower, if you insist on using it.

Correct, I can throw the switch and reconnect the ground so the solar will charge both house and van batteries. Since I'm a forgetful simpleton, the problem is that I won't remember to switch it off when I need to drive the van every time. That's the part I want to fix by hooking the trickle charger to the van batteries.
And no, I do not reconnect the ground after the van is running. The alternator is charging the van batteries at that point, while the solar takes care of the house batteries.
So I gather from your second statement that I can just run the + connection for the trickle charger to the van terminal on the 1315, and not have to run wire all the way to the van batteries? But where do I run the - connection? Can I just hook it a solid ground to the body or frame? The wiring diagram in the Blue Sky manual indicates that the wires are directly connected to the battery posts.
