Looking for realistic AH requirements.

I know this has been discussed before, please forgive me. My eyes are bleeding fro reading all of the other threads. Unfortunately, I cannot seem to stumble across the info I really need. Or its that i dont fully understand the lingo. Regardless..

Im looking for a realistic AH requirement for my camper. Ideally I would like the house battery bank to support this load for 48 hrs on a charge.

This is my proposed setup:

Lighting: 12watts (1A) (6 hr per day)
Radio: 24watts (2A) (4 hr per day)
CO/LP monitor: 1watt (.09A) (24/7)
Battery monitor: 1watt (.09A) (24/7)

And the thirsty one...

12vDC fridge: 40watt (3.34A) lets assume 2.5A average?? (24/7)



With this said, could somebody please help calculate my AH needs.
And any battery suggestions would be helpful.

Thank you!!

Radio: 24watts (2A) (4 hr per day) = 8ah/day
CO/LP monitor: 1watt (.09A) (24/7) =2.4ah/day
Battery monitor: 1watt (.09A) (24/7) =2.4ah/day

And the thirsty one...

12vDC fridge: 40watt (3.34A) lets assume 2.5A average?? (24/7) = 60ah/day

Total 81 ah/day, 160 ah for 2 days
You want to only discharge to 50% so you need 320 ah of battery. That's 4 6 volt golf cart batteries (464 ah or so for Interstate u2200).
Less money - Sam'sClub. More money Lifeline AGMs.
