Residential Frig Install ??

Depends on how long you want to go boondocking. We have a Samsung 197 with 4
house batteries and 2000 watt modified sine. Have used for about 1 1/2 years with no problems. If off the grid I run the generator for about 1 hour in the morning and 1 in the morning we're good. The alternator on the MH keeps the everything charged while we are driving.one of the best mods we've done.

As long as you don't exceed the inverter's 2K watt limit when adding the fridge to whatever else the inverter happens to be powering your current inverter should suffice. Whether you need additional batteries depends on amperage demand and length of time you intend to power these devices with your inverter without draining batteries below 50% capacity.

Existing is fine.

About the only thing I run on the invertor would be the entertainment equipment.....anything else, like AC's, Microwave, I turn on the generator.
If the engine alternator keeps the batteries charged while driving, then I don't see a problem there. The only other problem, might be dry camping.........and if I had to run the generator in the morning for awhile and the evening for awhile, I don't see a problem, for the type of camping I do.......actually, I do very little dry camping........genertor is always there if I need it.

I have 1000-watt inverter running from only 2 Trojan T-125 batteries. It is powering a 10 cu-ft fridge at 1-amp. I went tailgating recently without an issue. I precooled the fridge Thursday night from while plugged in to my house. I started off the trip on Friday morning, ran the generator for 4 hours. On Saturday, I ran the generator for about 4 more hours. On Sunday, I ran the generator for an hour.

Next weekend, I went on a trip 7 hours one way and then 8 hours back.

I never had a problem at any time with low batteries, but then again, I wasn't trying to go several days on the batteries alone.

I would imagine that 4 batteries would be ideal.

We have a 1K inverter and two 6v batteries by comparison and have no plans to change it, as we're running the OEM fridge on it now. Naturally it won't last all that long without power, but it does serve most of our purposes and especially while going down the road.

Yeah, except it's never simple and we don't know if the OP is never going to stay more than one night without power or if he's planning on boon docking in the desert for a week or more. I mean if you just want to run a fridge, even 500watts will do that easily and the amount of battery power will dictate on how long you can do so, before the inverter trips out.

We did the switch from the Not-So-Cold that lived up to it name to the Samsung 197, wife loves it pluse it keep the beer at 38deg and the ice cream at -2deg. I have (4) 6v batteries but I did switch the inverter to the Magnum 2812 just because things run better on PSW, like house current. I will be hooking up an Auto Gen-Set start that way if the batteries drop below 12.2v the gen-set starts.
