Residential refrigerators solve the many problems in propane types. Propane types are slow to cool, and have difficulty keeping cool in very hot weather. Also, propane types demand you keep the frig level when parked. If you read enough posts, you will read about many "fixes" to attempt to correct these faults. Residential frig does not have these faults and work in an RV the same as they do at home, and do not use any more energy.
RV refrigerators are primarily Ammonia Absorption cycle, not LP. LP is used to power the cycle in the form of heat. So is 12v power. When it comes to actual energy consumption (power used to cool) the Absorption systems are way more efficient than compressor based residential units. But the trend is now to go toward safer technologies for RV's like residential refrigerators with inverters, and large battery banks.
