Have it, Love it, didn't buy the camper because of it and probably wouldn't be a deal breaker without.. We probably cook more in the outdoor kitchen than indoor but that's more of a preference of enjoying the outdoors and monitoring he cat on his leash :)
I think and by the sounds of other posts they think as well that it depends on your 'likes' and your situation.
1) our camper is ALWAYS plugged in except when towing and we rarely travel longer than 1-2 hours for weekend camping so 'fridge on road' doesn't matter as everything is still cold or frozen when we get there.
2) It's a his/hers thing. :)
3) If we had kids, it would be a completely different review because it would be stopping the in/out camper all day.
4) It really is nice to have snacks, cold wine, sink, drinks at your finger tips when you are kickin' it by the fire.
I can confirm both the pros/cons mentioned in other posts... Have had non-level sites and at 6'4" i have to squat to fit under the open fridge door. We have had fridge defrost on the road during longer roadtrips as i forgot about it, etc.
