I have a golabs 500 watt all in one "solar generator" with a surge of up to 1000 watts and it won't power even a small fridge that when running consumes only 80 watts. The surge is just too high.
So I bought a 100ah 12v lifepo4 battery and then a 1000 watt inverter with 2000 watt surge and it still would not power the small fridge either, nor would it power a very small window air conditioner. So I got a 2000 watt inverter with a 4000 watt surge. It's able to power either device or even both at the same time.
This particular unit can just barely keep up with the continuous run power. And even if it keeps up, it runs for less than 3 hours.

the ecoflow unit I bought has 3300W surge. and the dehumidifier is 850w, 8amps, and 1.95 Energy Factor (L/kWh). I think we should be able to use it.

My use case is a little different. I have it in case we get a tropical storm or minor hurricane roll through. I have a 7.0 cu ft freezer that this should be able to power for a while. Knowing a storm may be coming, I would put roughly a 24 pack of water bottles in it (over time, not all at once) to freeze. Then when I lose power, quickly remove maybe 18 of the water bottles and put them on the top shelf of the fridge. Then shut the door and don't open it for as long as possible. Move what will fit from the top freezer to the freezer. Then plug the freezer in. Should keep the freezer going at least 7-8 hours, or more. Once spent and the storm is through, I can use the multi-adapter charging to get some more charge on it through my vehicle.
The hope it to do enough to get by about 3 days - fingers crossed. I'd lose the top freezer's stuff not transferred but that's better than losing it all.
i was also thinking of doing a diy setup as all i really need is a battery, a 12v outlet, and a way to charge it when we are using the truck. the inverter, built in MPPT charger, etc isnt really necessary.

In a pinch, use frozen gallon water jugs if you have the space. They will last much longer than the 500l bottles.
Given your use case scenario, why not just get a Eco Flow, Bluetti, etc. A couple of solar panels and use both appliances? Just be sure to get a solar generator that will charge at 80 to 100w.
And, in extended storms and such, getting gas is near impossible. Even propane becomes iffy.

I use a 300w inverter to charge my solar generator since I'm driving 4 to 8 hours a day anyway. (USB C connector, not the 12v plug)
Shut the truck off, turn on the generator, and I can power 12v fans, charge all my devices, (4)
and have plenty of battery left 8 hours later.
This is the same setup that a lot of people use to power a cpap and 12v (dc) refrigerators.
