Most replace with a 18 Samsung which will run on a MSW inverter (has DC compressor) BUT it’s 6” taller...will come through your Beaver’s door with its doors off. I put in a 21 Whirlpool which almost fit perfectly (ended up 1/2” to tall) BUT I had to take out the driver’s side window to get it in as unlike the Samsung it’s not counter depth. Put in a dedicated PSW inverter to power it.
