More batteries? Maybe later, as for now I don't have any issues, I am satisfied with my setup.

You are forgetting one little conversion, that being from 120 VAC to 12VDC thru the inverter to calculate what is being drawn from your batteries.

A 4 amp load at 120 VAC will translate to an approximate draw from your batteries of 45 amps including inverter efficiency. At 50% duty cycle for the fridge, you will still draw 22 amps from your batteries EVERY HOUR OF
OPERATION.

Since you should not draw your batteries below 50% depth of discharge very often if you expect any longevity from them, and based on the standard Airstream battery bank of 160 amp/hours, you will have an effective reserve of 80 amp/ hours in your batteries.

At 22 amps, you can run your fridge for 4 hours. Any quality battery monitor system will display the instantaneous draw from your batteries and the total draw for a given time period.

This is the main reason that I use marine refrigeration over residential every time. They draw 4-5 amps DC for the larger units with Danfoss compressors and have better insulation and cooling efficiency.

Residential Refrigerator Replacement

Better is always subject to our expectations, and reality is always superior to theory.

You can see by my measurements that the load of my inverter and refrigerator combined is less than 8 amps, and I will state without a doubt that my two batteries will run my fridge for way more than eight hours.

The readings I took above were taken directly off of the negative cable feeding my inverter, the draw represented on the meter is inclusive of load and inverter overhead.

This is good stuff. I just replaced my fridge a few months back. One of the salesmen mentioned why not use a residential and the guy said I had an Airstream and "oh" due to space I guess. Look at this one:

Whirlpool 10.7 Cu. Ft. TopFreezer Refrigerator White WRT111SFAW - Best Buy

My dometic unit is 53 3/4" H x 23 11/16 W x 24" D - not exactly the same but close.

The Haier unit mentioned is a closer fit to the Dometic I believe at 59.21 H x 23.62 W x 23.42 D especially in the depth (without handles measure). So, without handles it is actually 23 something J. Morgan.

I bow to the experts. Please forgive my intrusion into your conversation! I will keep my experience, training and knowledge to those that request it.

I did not intend to offend Lewster, I was simply pointing out that I know what the fridge draws and that your run time estimate is way off.

Of course I might just be a liar for lying sake .....

I have used it from NM, to AZ, to AR.

So far so good.

Everyone likes their own brand, but on occasion some folks have different expectations, different uses, and can arrive at a solution that is different from "the norm", but effective for their circumstance.

Got the new fridge installed. Fit almost perfect. Just needed 2" aluminum trim to cover small gap. It is very secure, doesn't wobble at all. And it gets cold!! Way colder than the previous one. Not very loud. And there is a ton more room inside, especially because of the adjustable shelves.

Before, we couldn't even fit a frozen pizza on the freezer, so this is great.

From what I see of the inside of that trailer, I like it. Looks really homey and dignified at the same time.

The fridge looks great too .

Thanks J. Morgan!

It is a work in progress with so many plans on the drawing board.

One of the biggest impacts of what we have done so far is painting the cabinets. I struggled with it for 2 years. Felt so guilty because they were perfect wood cabinets. But in the end, this space is too small for the country cabin look. We are very happy with the results. Just have to finish the bathroom and the bedroom now.

Well from what I see I like your decision to paint your cabinets, and the mild contrast on the painted walls looks great. I envy the style your trailer demonstrates.....
