Measured duty cycle on my absorption fridge is 2:3. i.e. on for 40 minutes and off for 20. This doesn't seem to vary with ambient temperatures much.
It takes mine about 7 hours to cool down--duty cycle of 1:1
Once it starts to cycle energy demand is 5.7 KWH per day.
I suggest getting a danfoss compressor unit--one that runs on 12 volts so there will not be inverter losses.

Thanks for all the info.
My goal is to reuse parts from old camper and the big Dometic fridge performs pretty well, that's why I am reusing it.
Don't know about alternator duty cycle. The bus has electric cabin heater as well and even I can't find precise data, it has to be >1000W.
I hope that working in cooled interior loop, the fridge will have to work less, than with original set, what was circulating air with triple digits temperatures around the coils.
Lot of the stuff goes under elevated dinette floor. Water tank is on driver side, so I put w/h and battery on passenger side. W/h running on electric doesn't need any vent beside safety valve drain, when battery is a type with venting tube that will go thru the floor.
Now I am working on electric panel. Original is having pretty big converter, but I am planning to use it. I plan to stuff it deeper under the dinette, only with access to front panel, but in case of any bigger problems I will have to take dinette off (about 1 hr) to make access. I think this will be acceptable.
Just to make it clear, I am making the conversion with fast trips in mind, not prolonged dry camping.

So this is my set before doing electrical.
Another question. I want to put 6 belts in the dinette, who is going to be elevated.
Sprinter has 2 factory anchors I can use for belts with M12 (about 1/2") threaded holes on the side, what is good. Than the bus had wheelchair lift installed and the converter add 2 more anchors on the sides, but in 7/16" diameter. Than I have grab bars in the rear with M8 factory anchors.
When I don't intend to make the van having full rollover ratings, the 7/16" added anchors seem to be on weak size?

I have an all electric B that I bought 2 years ago and still sorting out the occasional time that I don't have electric hookup. Haven't tried to push how long the compressor refrigerator will go on my one battery, I intend to add a second but I think that still will only get me about a day. When I know I am going to be off grid I carry a small 1000W inverter generator to recharge as needed.
I solved the cooking problem with a small Butane stove, doesn't take up much room and I carry a few extra cylinders. The one I bought below, can also be used with propane and I cary the adapter but no cylinders, I can buy them anywhere if I run low on Butane.

I have 1000W inverter generator as well. Even I have big Honda for years, when fellow forum member gave a tip about HD having them on sale for $150, I just could not refuse to buy it .
For years I have propane burner that screws on top of small cylinder.
Used it on the boat, but one time, while cooking on the beach my wife kicked the pot over.
So potatoes were extra crispy that day . Only lately I found I can buy enlarged shoe for the cylinders.
Even I have electric cooktop, I never used it in RV. I found out my favorite is toaster/oven, where I can bake kielbasa, zucchini, onions and tomatoes, while potatoes are easy to bake in microwave.
So I plan to carry those 2 units in this van, although they will have to go under the bed for travel.
I already build smaller cabinet on driver side, who will have to serve as wardrobe, leaving narrow side for shelving. Maybe small appliances will fit there for travel and countertop will be good place for using them.

Keytag1,
I love my NuWave induction cooker. They are more efficient and that's always desirable. The best feature is being able to move the temperature by as little as 5 f. Add a dutch oven and bingo out jumps a slow cooker.

230W panel, two 6V batteries. We use the crockpot as we are going down the road. Lunch or dinner is ready by 2 p.m. Electric blanket comes on at night on low under the fitted top sheet. Works great, little to no power.

Thanks for the tips about induction cooker.
I had induction cooktop in my rental years ago and it did not work with tenants too well, so did hesitate, but now single burner is cheap enough, so I bought 1 on amazon.
I am a bit confused. Cooktop manual says I need steel pot, when aluminium pots have label on them that I could use them?
Will have to make some experiments, but now, I am getting exited when projects start showing what it is going to be.

If you want to heat your water while driving you can also look into a heat exchanger using the engine to heat your water.
