Driving with LPG?

[mikep]

I just purchased my first Travel Trailer. The refrigerator works both on 110V and LPG.

If I want to keep the fridge/freezer running while driving, should I keep the LPG open and run it off of that or I also have an inverter that I guess I could use.

What do most people do?

Thanks,
Mike

Leave the LPG on, I leave mine on 24/7. You will need a generator for the 110v while on the road. Leave the fridge switch on "auto".

You didn't say what year, make or model TT/refrigerator that you have, so all answers will be more or less generic.
Being that you have a inverter, you could run the fridge off of it, "BUT" a fridge running off a inverter will pull some where around 40 amps DC from your batteries (actual load will vary by fridge). This is a very large load for your alternator to try and keep up with along with all the other systems that are needing DC at the same time. (New vehicles demand a lot of DC current to operate and run.)
IF your TT fridge has a electronic ignition, then by all means leave it on LPG and just remember to turn it off when stopping at gas stations or when having propane tanks refilled. If your TT has a pilot light, then there is a good possibility that the wind will blow the light out.
A RV fridge that is all ready cooled down for a minimum of 24 hrs loaded with items that are already frozen placed in the freezer or cold placed in the refrigerator section will stay that way for 8 hours with out any problem as long as the door is kept shut, so don't worry about running the fridge if you have a pilot light model.
Side note: Before everyone starts saying new refrigerators are all electronic. Norcold and Dometic both build low end units that still use pilot lights, they are cheaper, (require less electronic circuits), guess which units RV manufactures like to toss into the low end model RV's, pilot light type, same goes for water heaters, and ovens. You pay more for electronic ignition models.

We have been traveling in Travel Trailers and in Class A's... when underway we keep the refer closed and everything stays cold/frozen until we pull into the campground in the evening. You really don't need to run the frig while underway.

I leave my LP on all the time (except when fueling),the fridge runs on LP, from the time I unplug it from my house, till I plug in at the CG.

Thanks for all the answers.

And it is an electronic Dometic refrigerator.

I have been leaving the LPG on, but it hasn't been staying very cold on the road.

[whodo]

Have you checked to see if it is on the Dometic recall list?

We don't drive w/LP on. Our food stays pretty cold by just leaving the door closed as much as possible while traveling. I usually turn the frig. to the coldest setting the night before I know we will be traveling. 8-10 hour trips and the food is still good.

We do the same thing that Stampgirl does... leave it on the coldest setting the night before travelling. It works for us too. I've also been told by several RV'ers that you're fridge is not designed to stay "cold" when travelling. Most are made to keep things "cool". I don't know if that's the truth or not but it may be something to consider.

Have fun

We've been fulltiming for 3 years with 100,000 miles and always leave our Propane ON - except for some tunnels that require it to be shut off. No problems. The "when fueling" scenario is interesting. We don't shut it off ... have been told the problem with fueling is sparks that ignite gasoline vapors. If you feel safer, shut it off ... but don't turn it back on until you are away from the refueling point.
We pull a 30' fifth-wheel and the refer is about 35 feet away from the fuel nozzel when filling with gas.
Safe and Pleasant journeys!

we bought 2 cheap wireless outdoor thermometers from Walmart. We wrapped the outdoor units in a baggie and placed one in the fridge and one in the freezer. We put the indoor monitor screen unit on velcro on the side of the fridge. Actually I have one monitor screen in the storage area so I dont even have to go into the trailer. Now we dont have to open the door to see what the temperature is inside the fridge or freezer. I never run with the propane on as it is to easy to forget when you want to pump gas.

The DW and I found out the other day as we were traveling, with the frig on gas, and extra things in the ice cooler. We used up some left over from when we left the house, and deciced to put the rest from the cooler into the frig. Well what to do with the frozen freezer bottles we had in the cooler?? We placed them in the frig on their sides one up top the other in the middle, and one down low. Went back to the frig a few hours later, and behold it was around 7to 8 degress cooler with the bottles in the frig. Later, when one was defrosting some we place it in the freezer part of the frig and started over again when it was frozen. The bottles are sealed and got the jell in them. We were out over a week and never had it so good in our frig. Just a through, that's what we did to keep things colder. Good luck.
