It really depends on your electrical systems and the battery size/condition. With today's modern electronics it is not surprising your battery only made it 2 days. As an example on my FW (prior to battery bank upgrade and solar) if I left the battery carrying hotel loads with fridge on auto/propane it would get low enough in voltage at day3 to shutdown the fridge. This is with no lights/pumps/other stuff. Turns out my FW draws a little less 20 AH in day just carrying that load. With a standard GP24 marine battery rated at 80 AH then 3 days would definitely kill it
Make sure your fridge door heater is off, TV amplifier is off, and minimize lights to maximize time on battery. Good rule of thumb is one battery per night but again that is just estimating.
Also that 1 hour recharge by the auto place didn't really charge the battery. If it was as low as you indicated (and you have the standard WFCO) it will take at least 40 contineous hours to recharge that battery and potentially longer.
