Easy

Everything seems like it will work for me.

The refrigerator was at my home in 3 days!!! Was 300 dollars cheaper than even Amazon and just a quick getting it. Far exceeded my expectations and will absolutely order from them again. It was bought to replace a furrion 10cu ft fridge that gave out after a year and 4 months, very disappointing. The fit was right on the sides but did not have to trim anything to fit it in and the layout of the inside is much better than the furrion. I ordered the mounting brackets and sour patch thru a different company and still have not received them.
