Residential Fridge Misc. Topics

Since I've made the tentative decision to replace my Dometic with a Samsung when we return from our summer trip I've been mulling over a few details. One of those is securing the doors while traveling. I've seen quite a few OEM installation where they used a device attached to the freezer door with a little "J" hook that rotates up and grabs the two fridge doors. What are they called and where can one find them??

Second is the age old question of power use when on the inverter.

I've seen several post where (sometimes)a second dedicated set of batteries and a separate dedicated inverter is used and I don't understand why that is better than just tapping into the the existing inverter and battery bank. Looking at the battery loading it would appear that the fridge would draw roughly 19 amp while running which isn't insignificant but still not that bad since it does't run all that often.

Has anyone played with the duty cycle?? It would seem that raising the freezer temp to....10 to 20 or so and fridge to...42 would really drop the load power requirement and the temps would be in the range associated with an absorption unit.

Thanks for any input.

    My 21 CuFt draws 8-8.5 amps DC... less than a 100 watt light bulb and my educated swag on the duty cycle of less than 60 percent.
    I went with a separate battery/inverter/charger/transfer switch mainly to increase my charging amps and to run the AC compressor with PSW power... not necessary with the Samsung as it has DC compressors. My 2012 inverter/charger has never put out it's rated 100 amps charging (closer to 60 amps) so I added a 100 amp charger and can tie my two systems together when using the generator to recharge the batteries.
    Based on three months of using this system, I can go 36 hours before needing to recharge my 500AH battery bank which is twice as long as the house battery system... 800AH. Two 125AH batteries would be a better match although I do run a Sat receiver/DVR/TV on this system which I leave on 24/7.
    I used child proof locks to keep mine closed.
