Dutch_12078 Posted May 20, 2018 Report Share Posted May 20, 2018 I think it's odd how concerned we seem to get about driving with a refrigerator LP system on that's pressurized at about 0.4 PSI, yet we regularly drive with an engine fuel system that's pressurized at 40-50 PSI without a second thought.

Absolutely! Far more danger from the fuel line from the fuel tank to the engine than the propane tank and lines in the RV. To be safest, we should only drive electric vehicles.

keepitlow Posted June 28, 2018 Report Share Posted June 28, 2018 I run on 12v while driving, although sometimes run on propane. In 90+ weather my small fridge does OK, better in 80 weather. Link to comment Share on other sites More sharing options...
richfaa Posted June 30, 2018 Report Share Posted June 30, 2018 I do not know if it is 100% safe.I do not know if it is right or wrong. I can tell you what we do.That does not mean it is right or wrong. We travel with the propane on. We have been doing that for over 25 years. We fuel with it on.That does not mean it is right or wrong or safe.. We do have a residential upright freezer in the rear of our 5th wheel it only runs on 120V. We have the freezer temp set - 5 degrees. We can run a 8 hour day in the summer time and the freezer temp may go up to +5 degrees. We do not know how the RV fridge will react to no power for 10 hours as we have never tried that. We do not recommend that you run with it on because we do.

You most likely have a single group 24 battery in the trailer. In 6-8 hours of travel the fridge on 12V will use up most all the usable capacity of the battery, leaving you with very little to operate the lights, water pump, etc once you get to camp. Even if you always have elect hookups when you get to camp, you are doing a pretty significant discharge of the battery each day of travel, which shortens the life of your battery.

noteven Posted July 7, 2018 Report Share Posted July 7, 2018 My trailer has lpg-110v ac absorption fridge. I travel with propane on. On my pickup & camper with 3 way fridge I have an isolator under the hood and battery cables from it to bulkhead lugs in the box then to the camper battery. I have disconnected the + wire in the camper harness 7 way plug. The large cables carry enough current to allow 12v operation of 3 way fridge and other 12v loads while travelling without discharging the battery. The small wire in the 7 way plug would not. Plus it placed a draw on the truck starting batteries if any 12 v camper loads were used while the engine is not running. "Are we there yet?" asked no motorcycle rider, ever.

Kirk W Posted July 7, 2018 Report Share Posted July 7, 2018 Welcome to the Escapee forums! As others are suggesting, your refrigerator when operating on 12V would probably draw more power than the standard towing plug from the trailer to the tow vehicle is capable of supplying. The size of the wire limits the amount of current that wire can carry and most 12V refrigerators draw more than it can supply. Good travelin !...............KirkFull-time 11+ years......

RV_ Posted July 12, 2018 Report Share Posted July 12, 2018 Actually using the 12 volt increases the chance of an electrical fire because of the high amps of the electrical heating element. Most car and RV fires are caused by wiring not propane. Or hot coolant or fuel leaks. Go here and read the articles. https://www.bing.com/search?q=what+causes+most+RV+fires%3F&pc=MOZI&form=MOZLBR Read the links I posted earlier for the expert advice of Ed Lee Sr. about the safety of running with the propane on. http://www.rvnetwork.com/topic/131372-keeping-rv-fridge-cool-while-driving/?do=findComment&comment=945476 Good advice on upgrading your battery/ies if applicable.
