Thank you for all the quick replies to my question on running a R/R.
Happy Camping

“replies to my question”??? In 8 hours I’d say 8 degrees if you do not open the doors. Some will put a gallon of frozen water from the freezer into the refrigerator.

A 500-600W inverter will run a residential and a 1000W will let you add TVs and Sat receiver.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

I can travel literally for unlimited hours with a 1,000 Watt Inverter powering my Full Size KitchenAid. Get to my destination, Freezer "0" Frig "38" just as when departing even in 100 degree weather.

In Texas heat, I wouldn't unless you want to install an inverter to power it from your batteries while travelling.

Do you have a good charge line from TV to 5vr? I would use an inverter.


This has been discussed many time before. With any tow vehicle built after about 2000, there is inadequate voltage delivered to the trailer to charge those batteries as the charging voltage at the tow vehicle battery is only about 13.2V after the engine warms up. Adding a heavy gauge charge line will not help.

Whether this is sufficient to keep and inverter running is a toss up ! If you want to keep the trailer batteries charged (so that they have plenty of juice when you make "pit stops" on the road) you really need to invest in a DC-DC charger. Redarc, Renogy and CTEK all make one.

Many many posts about running a R/R using inverter and none to my knowledge have had trouble with excessively depleted trailer batteries. This is not off-grid camping where you are looking to get depleted batteries full while in transit. If the battery is a bit low it gets charged at the next destination.

our first TT had a residential fridge which i miss greatly compared to the propane fridge because we don't boondock or off grid camp but thats a whole other issue

we made several 9 to 10 hour trips with an inverter and 2 cheap wally world hybrid deep cycle batteries. never had a depleted battery.

i ran the fridge off those batteries parked at home in the middle of summer heat 24 hours and still had approx 75 percent battery left though i never wanted to drop the batteries below 50 percent charge.

Please prove me wrong ! I keep saying that modern vehicles regulate the charging voltage so low (<13.2V) that you can not hope to RECHARGE a depleted house battery even after hours driving.

My request is
• Deplete the house battery down to say 80% SOC. Measure the voltage at the house battery.
• Measure the voltage at the starting battery.
• Start your truck and immediately measure the voltage at the starting battery AND at the house battery.
• Let idle for about 10 minutes and measure the voltage at the starting battery AND at the house battery AGAIN !
• Hold the engine speed at about 2000 RPM and measure the voltage at the starting battery AND at the house battery AGAIN.

I used to run a normal absorbtion fridge off an inverter. It drew over 30 amps almost continuously and the standard charge line from the truck kept up just fine - even at idle. Granted, I would not plan on charging low battery's very much during this time.
Don't over think this like the folks on this forum love to do. Get yourself a 1K pure sign inverter wired to a couple of batteries and you'll be just fine. Thousands of new TT's and Fifth wheels work this way and have no problem at all.

Have you considered a DC compressor fridge or conversion?

I did the conversion, draws a bit more power than stated but it holds temp on the road.
