Why would two batteries run down with just the furnace fan. They run down overnight after being on charge for a week at a time. They show green in the window, but are a smaller marine battery.

Your batteries may be the victim of overcharging, if they are charged a week at a time. If the water level is constantly low, this would be a first indication. Many LQs do not have circuitry, that allows the maintenance charging cycles featured in "Float chargers". If the batteries are left unattended, they can overcharge, their plates will be damaged, and their capacities will be drastically lessened. They can still show a full voltage, but as soon as a load is applied, it will quickly drop off.
A furnace blower can draw several amps, and even with good batteries of a 700 -900 AH rating, it can use much of their capacity in a day or day and a half. Combined with other appliances and lighting, the batteries will be drawn down past the furnace's ignition, operating voltage. Without the blower motor operating, the furnace will then not work.
I would suspect the condition or age of your batteries as being the problem.

yeah, bought 2007 kieferbuilt used 3 times. Purchased 2 new deep cycle marine batteries. Got em' home and they were too big to fit in battery compartment. Now to rebuild compartment, or, find smaller deep cycle batteries.

The size of the LQ and the outside air temperature, along with a few other factors will make a lot of difference on how long those batteries last. My current trailer is an 09 Bloomer with good insulation and a 14' LQ. 3 weeks ago we ran the batteries pretty low with one night of 22-25 degree weather. The next week we sat all weekend on the batteries with the lows being in the upper 30's. There was a lot of difference in how much the heater ran between the two weekends, therefore a lot of difference in the battery draw.
