You asked 2 questions, so the response - I guess - answered both.
How long? - Weeks.
Dead in the morning? - No.
Though... let other people here convert (somehow) cranking amps into amp-hours and predict how long it would run on these batteries, given the unknown draw of your frig, say 10-20 AH per 24 hrs, mas o menos...
The propane... Again, depends on what frig. 7 cu.ft needs 1.5-2.0 lbs per day. So 2*30 lbs tanks will last about a month. One 20 lbs tank - 2 weeks or less.
