Denny Wolfe installed this Truckfridge TF 130 12 volt 4.2 C.F.
in his Lil Snoozy. I emailed Richard Micle at Lil Snoozy today to see if he would install this refrigerator in our ordered Snoozy, but no reply as of yet.

It's the same truck fridge Denny put in his snoozy
except it's dual voltage.

I'm curious what Richard's response will be. Please keep us posted.

I have been thinking about the same conversion for my Snoozy. Thank you for the instructions and the incentive to save up and by the fridge.

When I visit LS and talk with Richard Friday I will ask him about the email and if they will do the fridge on purchase.

Another important installation note: the fridge must be moved 3/4" out (toward the center of the trailer) to allow adequate adequate air flow in under the bottom, up the back and out over the top to cool the condenser.

It fits with the mounting flange fastened to the Snoozy cabinet face but the back bottom edge is nearly touching the wall, impeding much airflow. Because the snoozy walls are curved there is about 3" clearance at the top and I mistakenly assumed there would be clearance at the bottom as well. Not so.

The fridge was not slid all the way in when I first tested it and reported the 23ah in 24 hours power consumption. Yesterday I put some room temp food into the room temp fridge and turned it on. It ran continuously for two hours and the top was noticeably warm. After I moved it away from the wall 3/4" the compressor began to cycle on and off as expected. After an hour or so the top no longer felt warm.

We are off to camp tonight at Paynes Prairie near Gainesville Fl tonight. Even though we will be plugged into shore power there I'm going to leave the battery charger turned off and take notes on 12v consumption.

Power consumption with the fridge running and other 12v loads measured while actually camping:

5:00 to 10:00 PM fridge opened and closed to make dinner plus two hours of fantastic fan plus led lights after 6:30. = 2.0 ah/h
10:00pm to 7:00 am. Just fridge running = 1.5 ah/h
7:00am to 10:00am fridge plus some lights plus some inverter/cell phone charger use = 2.4 ah/h.

Ambient temps were about 80F during day, 65F at night.

I'd guess our total usage would be around 50 amp-hours per day, depending on ambient temperature. At 50ah/d two days would use 45% of our battery bank, three days would take about 70%.

The tow vehicle fully charged the battery from -30ah plus offset the fridge usage in three hours driving.

It's considered best to avoid discharging the battery below 50%, IIRC. So if dry camping for more than 2 days, a charge from some source would be preferable to maintain good battery condition.

Another data point: 24 hours, 65F at night, 80 during the day, no shade. A couple of hours of lights, four hours of the inverter charging cell phones. 47 ah used.

I was at LS Friday speaking to Richard about the LS. One of my wants is the 12v fridge option. Richard said he was looking into it and spoke very highly of you and how knowledgable you were on the issue. I felt he has some great ideas for LS and is going to bring it to the next level. He said the they we're check the LS power /wiring etc. to assure the fridge will work with the current set up. I thought he said he was checking on the Norcold but not sure?

I really apologize for my ignorance, but what was your main purpose in replacing the Magic Chef refrigerator in your Lil Snoozy? It sounds as if the original unit failed. However, it also sounds like it gave you a good couple of years of service. You paid $700 for the 12v fridge. I commonly see those dormer style refrigerators at Lowes and Home Depot for $150. I could buy 4 of them for the price of the single 12v unit. I could just throw out the old one when it failed and slot in a new one. Doesn't this seem more economical?

Can you please explain your reason for going 12v?

Beginner, the reason that we had replaced our 3 way refrigerator in our Scamp, and will be doing so in our new Lil Snoozy, is the fact that it is sooo simple to use. It connects directly to the battery, uses very little amp hours to run, cool/ freezes very fast upon startup (no matter what the arizona temp is), is able to be run while traveling, does not have to be level to operate, has a larger C.F. interior than a 3-way, and does not need venting to the outside. We rarely camp where electricity (110 volt) is available, and I am not wild about using a generator (no matter how "quiet" they are supposed to be).
Hope this helps.
Dave & Paula

The 12v unit is nearly twice as efficient as running the dorm fridge with an inverter. That means nearly twice as long dry camping.

The dorm fridge got hard to start (on the inverter) after just a few months. I wasn't confident a new one would work any better.

Upgrading to a 1000 watt inverter would cost about $500 and I'd still be dealing with 75 amps on the 12v side of the inverter and the attendant voltage sag problems that can cause the inverter to fault out because it thinks the battery is almost dead.

The 12v unit was much more expensive than another dorm fridge but it it is made for the RV enviornment, it's quieter, much more efficient and should last a long time. To me that made it worth the extra money.

It's all about camping style beginner.
I can live without a fridge now.
My daughter no longer takes shots
so we don't need to keep medicine cool.

We're still anchored with wife's mother,
so are camping style is campgrounds with
power right now.

It would really be nice to have it run while traveling,
so that would be the logical solution.

And it's the old addage: Pay me now, or pay me later.

So things are calculated by short term and long term solutions.
