Not my pic, but ours has the same fridge:

Our rig also came with an 1800W Xantrex PSW inverter, and 4 house batteries.
I can run the fridge from shore power, the onboard 5500W generator, the inverter via the battery bank - which can be recharged while driving.
Our previous Class A had an absorption style fridge. The only advantage it offered was being able to run from the onboard propane tank if boondocking for an extended period without power. But that's where the advantage ends. I had to manually defrost it monthly while living in the RV fulltime for a year. PITA!
This fridge is HUGE by comparison, and works far better.
And as others have said, a long way from a $100 fridge!
