residential fridge while towing

I have a 2017 vibe 313bh. My truck supplies 12+ out of 7 pin. Has anyone ran fridge with inverter while towing?

It should work. For me, I went with small 2000 watt Honda to power refrigerator while traveling. Easy to set up if wanted and less complication than the battery solution, but can be done. May want an extra bettery or two possibly?

I have two Honda gennies (only need one for refrigerator) mounted to my back bumper. I use a cord to go between generator outlet to trailer inlet and powers trailer which I only power refrigerator while traveling. One small tank of gas for genny runs all day on generator.

We run our residential refrigerator off of the inverter while towing all the time, with no problems. Cold stuff stays cold, frozen stuff stays frozen.

Ditto. Truck recharges the batteries. Works great.

If FR puts a residential refrigerator in a trailer, don't they automatically install an inverter to run the fridge off the battery/batteries?

Yes, the inverter is enough to run the residential refrigerator for at least 8 hours of operation or more depending on the battery condition. Also, the residential units will keep the food cold longer than a RV fridge when not powered up. A RV fridge will normally keep food cold for 24 to 30 hours when not working and the door closed. A Residential fridge will keep food cold and edible for up to 96 hours under similar circumstances. Why the residential unit has better insulation to retain the cold in the fridge.

Hopefully the dealer installs a decent, true deep cycle battery (or 2)!

My trailer came with a RV refrigerator. We had the dealer swap out to a residential as part of my deal. They was going to do the inverter also, but I had them to not go that route for myself. Not against it, just chose the generator option as most always, nothing is needed as food stays cold as long as doors stay closed and traveling.

That SRM-24 Interstate battery works for us but we have never camped without shore power intentionally. Even so, that battery that the dealer gave us will be 3 years old next year so I'll replace it with a 12V Trojan flooded battery - something like a 27TMX or maybe even a SCS225. Our only experience without shore power was when we were fairly new campers. The campground lost power for about 6 hours starting just before dark. Our trailer at the time had all incandescent bulbs and they depleted our older Deka Marine Master battery pretty quickly. I've replaced all the light bulbs in our current TT with LEDs and we'll be much wiser about 12V usage if it ever happens again.

Residential Refrigerator

Just keep the door closed. It will hold the food for many hours. We have full-timed for 22 years with an RV refer, never ran with it on and nothing has ever spoiled.

The factory installed inverter will power your residential fridge going down the road using 12v power from your battery bank, which in turn is kept charged from your truck through the 7 pin connector from the camper to the truck.

Once you shut off the truck engine you should have about 8 hours run time on your Whirlpool fridge or about twice that long if using a LG or Samsung residential fridge. Of course, the more amp hour capacity you have with your battery bank, the longer you can run without either hooking up to shore power, running a generator, or starting the truck again while plugged into it with the 7 pin connector.

If your unit has the space, I'd recommend you upgrade to a pair of 6VDC batteries. NOTE, 6VDC batteries MUST be used in pairs that are wired in SERIES to give you 12VDC. If you can fit multiple pairs, each pair MUST be wired in PARALLEL. Multiple parallel pairs MUST be wired in SERIES.

My Super-C 2014 Dynamax DX3-37RB has a large residential fridge. The TWO OEM 12VDC house batteries would be drained in LESS than 12 hours. There was LOTS of room in the battery bay so, I upgraded to SIX 6VDC batteries. With those six, 6VDC batteries, the inverter can power my fridge for about 48 hours. Of course, when I'm driving, the alternator keeps those house batteries charged. At my stick~n~brick, I run a 10 gauge extension cord to my rig. The 15A that provides, keeps my fridge running.

6VDC batteries have MUCH thicker lead plates and provide more amp-hours. Two 6VDC batteries wired in series (ie:12VDC) provide a lot more usable power than a single 12VDC "deep cycle" battery.
