No, no, no... This Furrion given in links above is not a Danfoss-style compressor, it is not efficient. It draws 15 amps, the real camping-style compressor fridges draw 3-5 amps max and do not need a spike of electricity to get the compressor started either. There would be no point to put that in an RV unless you are always plugged in.

I have one of these ICECO Compressor Fridgehttps://www.wayfair.com/appliances/pdp/iceco-211-cuft-frost-free-chest-freezer-ieco1002.html Though you will have to search another site to find specs...
I have 2 GC batts and could easily go 3 days without use of solar charging. With solar this will run indefinately

5 amps draw is the max any compressor DC powered fridge should pull, typically 3-4 is normal, and they run a few minutes only before shutting off, having reached the cold temp. As I said... 8-10 mins per hour total of run time seems normal. You can insulate the sides and top to make it more efficient, but I have not needed to do this yeat.
Also see ARB and Dometic for other more popular models.

The one you link is a 2 C.F. that is listed at 7.5 amps. The Furrion is 10 C.F. and is listed at 15 amps. I'd assume a larger fridge would use a larger compressor, and thus more amps. I'm not an expert by any means, but the Furrion appears to be far more efficient than yours, if you take into account energy use per volume.

I never measured, but I'd imagine mine runs about fifteen minutes every hour, but I keep it about 3/4 the way toward the cold side. I'd imagine if I put it in the middle, it'd run about ten minutes an hour.

Just looked up a 9 cuft NovaKool fridge/freezer on their website. Althought slightly smaller than your unit, it draws 5.2 amps which is in line with our 7.5 unit which draws 4.4 as per tester. That's almost 3 times more than the NovaKool unit.
