Residential Fridges

Yes. RV's with a residential fridge also has an inverter and increased sized battery bank. Some add solar to help if they plan to boondock a lot or just plan to run the generator a few hours in the morning and a few more at dinner time.
The inverter can be a smaller (1000W ish) inverter just for the fridge but most have a whole house inverter (2000W or higher) that also powers the fridge. Having the larger inverter is good if you also have a larger battery bank as the larger inverters will have a much better battery charger to top off the batteries quicker if you do need to run the generator.

X2 Most big rigs need 2-3 hours of generator time even without a residential refrigerator. I added a 2nd system (batteries, 1000W PSW inverter, and 100A charger) for my 21 cuft refer install. 2 batteries will power it for 30 hours before needing to recharge...longer than the house batteries. Best mod ever.

Mine setup with solar works well boondocking. Cloudy days, the generator may come into play.

I did a limited test, in the drive way.
Fridge is an Samsung RF18.
Inverter is a Tripplite RV750ULHW.
Batteries are 5-year-old T105 flooded cell. MH is on 30amp/110v all the time, at the house. Water level above plates.
All measurements were done at the battery terminals. Starting, I flipped the CB off and the bats were at 12.6. At 8 hours the bats were at 12.1 and I turned 110 back on.
