Parasitic battery drains

Make sure the fridge is on propane, not battery, while driving. The 12V option almost guarantees little or no charging. The inverter can have a small residual draw even when not in use. Disconnect it or make sure it is truly off when not in use. Leave shore power connected for a full day between trips for a full charge. 200+ AH dual golfers should last days for usage as you describe.  

What was their charge state to begin with? "Charged while driving" doesn't help us much.. You could have a 200aH "needed charge" and in an hour your eX can only send 30 or so back there through the Bargman connector, and if running the fridge on 12v, it ate at least 10 of them..


I have tested our standby loads, and show 165mA, and we have a couple remote control additions that sit and listen for commands.. Your best bet would be to use a multimeter to see what your steady state draws are. It easy. Just disconnect a battery cable, pos or neg will work, set your DMM to mA/A, or whatever setting it has for current that is appropriate, make sure you are plugged into the leads that match the expected current (I always use the 10A range/inputs) Then put your DMM in-line with the battery and cable, as a "jumper". You can do this with everything turned off, to see what draws you have all the time, and with some stuff turned on to see how much it draws.. but be careful with that, you don't want to blow the fuse or worse, in your DMM.
