JimK , you might already know this, but are you measuring amps to the battery with an ammeter or battery monitor, or are you going by the solar controller's display of amps?
The controller shows amps going to loads as well as any going to the battery. An RV will have maybe a 1 amp load all the time from various things always on. Loads come first with any amps, so you can have all the controller's amps going to loads and none to battery.
I have a compressor refrigerator so obviously that has to be off to determine the amps going into charging the batteries. I have no idea where you are losing 1 amp of current for "various things". Three or four LED light fixtures would pull an amp. I measure with the lights off as well. The radio is also off. There is only one other power drain and that is the propane leak detector at somewhere about 0.1 amp. I do not know if the refrigerator circuit board pulls any power. If so, it is too low to detect with my equipment and circuit detector.
