Residential Refridgerater

About the same as a house refrigerator.

When I installed our new 10 cu ft residential fridge, it took about 4 hours to reach normal operating temps at 70 deg.F ambient.

Today if the RV is not heated, it should reach 34 in a couple of hours. Warm, and it could take longer. 4 hours should be plenty of time.

Do you have a large inverter and at least 4 batteries?

I hope that you have a couple of solar panels too. If not, then I would be installing them. I do not spend each trip in a campground.

SunElec.com has some 140 watt 12 volt panels for $229 recently. They have the required aluminum frames, and because they are 12 volts, you can use a lower cost PWM controller.

Not long. Pluged in at home...ac runs fridge, inverter charges batteries unless you have a converter. On road, engine charges batteries; inverter runs fridge. Generator same as home.

Starting from 'off', I allow two hours and then load fridge.

Thanks for the information. I will probably plug in prior to leaving. I do have 4 batteries and a large inverter but it is naot an issue to plug in first. I just had no idea what to expect. 4 or 5 hours is perfect.

Mine has been running on the inverter going on 3 years, plugged in or going down the road. Dry camping in 6 to 8 hrs start the gen set for a hour or so to recharge the batteries.

Don't know what refrigerator needs 5-6 hr to cool down.
Maybe one that is filled up with warm food as I am getting ice in mine in 1/2 hr.
Small ice maker needs 7 minutes to dump first cones.
Nothing wrong with plugging it in night before, but compressors do cool down pretty darn fast.

Just for my FYI, can these larger residential units run off gas ?

No

If it's empty, less than an hour. It cools A LOT FASTER than a gas job.

Happy trails.
