Depending on who you ask there pros and cons just like residential and absorption fridges when used in RVs. If you are plugged into shore power you should be good to go unless unit is faulty. Do not know personally if they consume more power as compared to same size 120 volt fridge, but if without power hookups upgrades to replenish consumed amphours will be needed. Many manufacturers at least give options on fridge choice, 12 volt/120 volt are less costly, we prefer absorption for RVing.
I guess we have been lucky over 3 decades as as all our Dometics and Norcolds have performed well across 6 different RVs, it is well over 80 degrees today and I was just out in our RV and had a big glass of Coke with ice from the freezer, even 95+ degree temps have been no issue for our Norcold 4 door fridge. Without a doubt the biggest issue with absorption fridges is improper installation, on a few RVs I made modifications to both interior and exterior of fridge greatly improving cooling efficiency.
