After being disconnected for about 8 hours, readings at the battery terminals was 12.82. So it appears that the BT did its thing. When I checked electrolytes, all cells looked good. When I reconnected for float/maintenance, the red light on the BT came on again, indicating that it is charging. That has been the case for about 4 hours. So we will see how long it takes to go into float mode again.
I did get the Boondocker installed today, and made sure at least the converter portion was working. Seems good to go, but I won't get a chance to actually test it in the real world until the July 7th weekend, when my honey, and I take the trailer out again.
Thanks to all that helped, and I will let you guys know when the solar bug hits me.
