Getting Rid of a Residential Refrigerator

I've already decided that if our RV unit ever goes out, we'll be replacing it with a residential unit for less than $400 and with this smaller unit installed, I'll have room for a slide out pantry and won't have to cut out any drawers below. Still most sure it will have more room inside. Wouldn't want anything too fancy anyway and might have problems with running it on my mod sine wave inverter.
