You can run the fridge off the inverter while driving. Not sure about the incline on your driveway and how that will impact the operation. From what I've read, most RV refrigerators will work properly as long as they are within 2 degrees of level side to side and 4 degrees of level front to back. It sounds like you should be OK on your driveway, but you should probably check with an expert. Happy travels!
