Dometic portable fridge/freezer

We have one in the basement of our Fifthwheel and use it as a second freezer, have a residential three door fridge with bottom freezer. Thought the fridge freezer would be enough space, but since we're "Most Timers" approx 10 months in the RV wanted more freezer space.
Was going to run the Dometic freezer on 12 VDC while traveling, bet decided to keep it on 120VAC and added an outlet off our Inverter.
Been doing this now for over five years and not issues.

The lack of response suggests this unit isn't very popular... or, did I simply ask a dumb question? Was really hoping for a more robust response, thinking this unit was something RV'rs would consider a useful tool... but... no?

They come in some Class A's normally carried in the storage compartment on a slide out tray.
I have a MORryde tray mounted in our basement where ours lives, just pull out the tray to get into the freezer.
The cost probably stops lots of folks unless they're Full or Long term travelers and want/need the additional freezer/fridge space.

How ironic. We just purchased the Dometic CFX28, dual zone, primarily to use either tent or popup trailer camping as we have both including a fifth wheel (but may use it while FW camping depending on the need). We haven't taken a trip yet with it, but hubby meticulously researches before he buys and he liked this one. As a test, we plugged it in to our Jackery Explorer 1000. It draws 2w's and we've been running it now about 18 hours and the Jackery is at 85% power.

I'm planning to install a sliding tray for the pass-thru to hold the fridge/freezer, as there's a plug in there I can tap into, and it would be convenient to have it stored in the RV... but, until I do that, I'm probably going to put it in the back of my SUV, as I've got a 12V plug I can run it off there, too.

One of my concerns here is how much power it may draw if left powered by the SUV's battery system... from what I can surmise, it doesn't draw a lot of juice, but of course, I don't want to drain the SUV battery either.. any thoughts out there as to the workability of my plan?

Forget using your SUV starter battery. You need a separate and rather big battery for this. They draw A LOT of juice. I don't know how people measured 2W (??), this is too low even for a 28L single-zone unit. My 50L dual-zone unit by another brand, with freezer 4F and fridge 40F draws 30-50W. On a standby - no cycling - it draws 2W, yes.

What's the worst is that it runs 70% cycle with the end-result 45-50 AH per 24 hours at ambient 77-85. In a single-zone mode, no freezing, the entire box at 4F, 50L box should draw 20-25 AH per 24 hours. Maybe 20 AH for a smaller box. You need 100 AH deep cycle AGM or flooded battery to last you 2 days, for cooling only, no freezing. Or 50-70 AH Lithium.

We just bought one of these based on a review from Haylett RVs Youtube review.
We bought it to haul some meat across the state, and right now we are testing it as a beer cooler.
After 1 week, we like it.

My buddy raves about his. It's in a FWC TC shell model.
