I had asked this question recently and found out that this was not a problem at all. We went to Lowe's and found an efficiency sized refridgerator to replace our old Dometic fridge. When removing your fridge, you will notice a plug in from your previous fridge and it plugs right in. I can't recall the measurements, but the fridge will run right at $300 bucks. Also Home Depot carries them, but you have to order them.
