I have a Coleman 18HTT with a fairly decent sized refrig/freezer, I'm too lazy to go check the model at 11pm, but hopefully my picture will attach. I am going to be dry camping for a week and ...

LP consumption is easy to approximate.
1. A pound of LP gas has approximately 22,000 BTU.
2. The refrigerator in my camper -- looks like yours -- burns 1500 BTU/hour at maximum cold (highest heat). Note the data plate inside:
3. 22,000 BTU/pound x 20 pounds/cylinder = 440,000 BTU/cylinder.
4, 440,000 BTU/cylinder / 1500 BTU/hour = 293 hours/cylinder or about 12-1/2 days per cylinder at max cold -- per cylinder. Two of 'em will probably run a month.
As noted above the refrigerator needs 12v DC to power the electronics.

Chuck - I believe what's listed on your sticker is what the fridge consumes when it is running. So in reality, it will use much less than your total calculation, as the fridge won't be on all the time.
