Question:
Is this a suitable replacement for a Bigfoot Truck camper with a Dometic DM 2662 RBX? I currently have 200Ah of lithium batteries installed with 520 watts of solar, dc/dc charger and built in jenny.

It sure is Peter! The Norcold Polar Full RV Refrigerator w Freezer item # NC73FR is going to be a great way to upgrade your Dometic DM 2662 RBX. You've definitely got plenty of battery to power it too. It draws between 3 amps and 7.9 amps of 12v DC power with a average running draw of 5 amps. It is 12v only though. We don't carry propane powered fridges so you will lose that ability with this upgrade.
The Norcold Polar Full RV Refrigerator w Freezer item # NC73FR is going to increase your capacity from 6 cu ft to 8 cu ft while also being 10 lbs lighter. It fits in a 23-1/2" wide x 52-7/8" tall x 24" deep cutout and measures 23-1/4" wide x 52-7/8" tall x 26-7/8" deep. These dimensions are comparable to your Dometic but expect the door to stick out 2-7/8" farther.

Thanks for the reply. I will order as soon as the rain stops so I can verify the rough opening dimensions. Peter
