We had our minds set on the Everest for a good while. We were fortunate to get to see both models on the lot. We spent most of the day back and forth. The electric heater/fireplace with it's digital thermostat, the huge pantry, and huge back window were why we went with the mammoth. We however didn't like the double couch and needed an oven so we placed an order shortly after we looked at it. Was also able to look at both ec models and articfox. The other two didn't appeal to us at all compared to the host. Now that we've used our for a while, every once in a while the wife will comment that she wouldn't have been able to fit all our groceries in the Everest. Also the views out the big window makes the camper feel more open.
