If you are going to be boondocking with a rez fridge you are absolutely going to need a real battery monitor like the Trimetric or Victron or you will soon become a very UNHAPPY camper if you rely on idiot lights OR a voltmeter reading. Search for Victron or Trimetric here for more details.

BTW....I too would pay for a gas fridge for boondocking rather than put up with the hassle of a rez & charging. Occasionally is one thing but if that is how you camp most often then gas is the way to go.

I have a huge residential fridge, a dedicated 2000 watt inverter, an additional 1000 watt inverter (TVs, cell phones, computers, CPAP, etc) and 4 12 Volt deep cycle batteries.

Just installed a Trimetric and would never be without it. No more worries...and the reefer is really no problem. Run the genny a couple of hours a day, but since I am doing that anyway I have an electric coffee maker and don't worry about starting up for a half hour more since it always is putting amps "in the bank." With the trimetric I always know where I stand.

The panel idiot lights...are for...idiots.

My monitor didn't cost that much (maybe $150.00) and it was very simple to install. My battery compartment is right by my entry door so I installed the monitor on the side of my sink base which is right at the steps and by my water heater controls and slide controls.

Trimetric products are a great way to monitor many things about your battery including Ah-hours both in and out of the battery(s).

We have observed several large class A motorhomes that travel with a Honda 2000 generator to avoid operating their built-in diesel generators while boondocking. Quietly provides power for recharging and refrigerator operation. Also eliminates noise and vibration of the internal generator.

I have the whirlpool refrigerator. It is the 20 cubic foot. I have traveled 10 hours with no problems with inverter. I have installed a meter in the basement by taping off the hot side of the light in the water closet. I am comfortable based on my experience going 15 hours without any issues. Hope this helps using the inverter supplied by CC. This is with 4 - 6 volt batteries.

My Samsung 25 Cu.Ft French Door refrigerator uses an average of 2KWH per day measured on the 120 volt side. This is with inside temperatures averaging 72 degrees. It will use more as the temperature goes up. That equates to 180 Amp. Hr. of battery use every 24 hours. (180 x 12 volts x 92% efficiency for the inverter). Since you do not want to discharge your batteries more than 50%, it requires 360 Amp. Hr. battery capacity just for the fridge. The size of your battery bank and the exact usage of your particular fridge will determine your usable run-time.

Our works great and stays cold. it doesn't use very much propane and doesn't have much draw on my batteries. Remember, if you camp in cold or cooler weather, you will need to eventually run the furnace. Now you have 2 appliances that will draw fairly heavy from the batteries.

This is just my opinion. I would not buy the residential fridge. If it were me, I would opt for the large capacity 2 way fridge and pay the additional money to have it swapped into the RV. Then you are not dependent on running your generator or keeping the rig plugged in to keep your batteries charged up.

X2 - (at least)

If you are going to do any boondocking you will want this item made by Bogart Engineering. Trimetric 2030RV. Easy to install and it's an excellent way to monitor your battery in all the ways you will need. I looked at many different ones before settling on this one based on info on this forum.
Sure glad I did.

Go Solar

On our houseboat, we use a Honda 2000 at the end of a 100 ft. 10 ga. extension cord to run our freezer (frige is gas). Nice and quiet. We run it about 6 mehours a day and that is enough even at 100 degrees. Google HandyBob's Blog and it will tell you everything you need to know about solar. I use solar on my trailer, and it runs everything but the AC and microwave on a 100 watt panel and two batteries. The Trimetric battery monitor is the right answer, even if you don't go solar.

Wow! Thank You! I would need an electrician to install, but that is not hard. Thanks again!
