30mm only saves 3Ah per day over the standard cover and is hardly worth the trouble imo.

60mm however saves 10Ah and is certainly worthwhile - trouble is you now have a very large box to accommodate.

At the time I was trying to work out how reduce energy as I have no room in the engine bay for an auxiliary battery. We sleep in the car so had to find somewhere for the battery.

It is easier to move a larger fridge than battery each night & back to the boot in the morning. So in the end I use a fridge cover with Velcro exhaust side & 20 to 30mm of foam which adds very little weight. Replaced fan with a much better quality fan.

For boats they go a lot further, 150mm to 200mm is their aim as they have more room.

We had previously insulated the home hot water system & energy loss scrapes in under 1kWh per 24 hours simply to keep the tank hot. It was about 1.8kWh per 24 hours.

So I thought if I can save energy heating I should be able to save energy cooling.

Direct light, esp behind glass, is the really heat generator. Cover your fridge and other items with a reflective material and create flow through ventilation for the area where your fridge is located. I use an old windshield sun screen and crack two windows on opposite sides when camped. A forward facing sliding window is always opened a tiny bit when travelling.

I have cut out windscreen sun screens to fit every window, mostly for the night but also use them in day on the side the sun is hitting the car. (Double thickness for the windscreen)

As said above, ventilation, leaving windows open a touch with window wind/rain deflectors reduces heat build up in the car substantially.

Insulating the ceiling in the car, this also makes a big difference. I never thought that that much heat came through the ceiling until I insulated it.

When it is really hot we chuck a feather down sleeping bag over the fridge making sure it still has good air flow. It is surprising how much difference this makes.

Its all well and good to go chasing a bit of power saving but at what expense. Not talking money but time and effort some people put in to minor saving. Like chasing the sun with panels, buggar that, I have better things do with my time. Just put in an extra panel. My evacool would be 60mm thick standard I reckon. I just want to relax an not be troubled by any of it. We used to go for week with a swag and esky and a couple bags of ice, eat the things that go off quickest, first, beer in the creek was drinkable. Getting to complexed now
cheers

We sleep in the car so things have to fit in the limited space. We can't get a bigger car as it won't fit in the garage & street parking was already a nightmare a decade ago & we don't want to move house.

The ice in our old custom made esky lasted 10 days but after that we were stuffed & bought ice doesn't work. So improving an off the shelf product was the next easiest solution.

I did look at refrigerator kits & Aerogel insulation, money is not an issue, but wasn't able to get it as compact as hacking a fridge. Now I've done one it's easy to do a replacement when required.

As a side note, reflecting insulation to keep heat out works best on the outside of the window. With the reflective insulation on the inside of the glass, it gets heated twice due to the reflection heating the inside while the sun heats the outside. This heat then auto syphons pulling colder air in under the insulation layer and pumps it out the top. Stop the glass getting hot by insulating on the outside will greatly improve the efficiency and keep the interior cooler.
'Naturally, the opposite is the case in winter unless frost/ice is expected, then it's better to stop the ice building up on the window by insulating the outside as well as the inside.

Hi Darren, Engel is the only camping fridge I would consider. But I would shop around for pricing and dont rely on camping shops for the lowest prices. I see in your intro post you are from south east QLD. Ive bought several Engel fridges over the years from a truck dealership in Toowoomba. A lot cheaper than camping shops!!!! If you are near Toowoomba at least try Westco truck sales. You can haggle with them a bit more than a purely retail outlet like bcf. You could save a few pennies and buy a cheaper brand but what do you do when your fridge dies in the middle of nowhere?? Its all good to have a fantastic warranty, in the meantime you lose your food on your way back to a city to get a new one !! Regards Pete.


 IMO the best camping electric fridge on the market is definitely an Engel. As the ad says (not sure about the tax) "unbreakable".

My 'ol mate Roger Browne from ARB donated an Engel for my Simpson Desert crossing in 1981 which was carried in the back of my BJ40 (no tax).

I cannot remember the number of times the old Engel exlted the rear door as I charged the sand dunes in a 4 cyl non turbo 4wd and rolled all the way down the dune...beer included...only to be rescued and firmly replaced in the back of th BJ.

That battered and bruised Engel now keeps my beer cold at my holiday house 38 years later.

Buy an Engel!

Don't try that with a new Engel Monty, you won't have that sort of "never say die" performance from it. The old/early Engel's were worth their weight in silver, they were still heavy so gold was just a tad too much :lol: These days there are better, more reliable and more efficient on the market for less $$ that make less vibration noise and pull the temperature lower much faster. They might have been unbeatable once upon a time, but time has caught up and past them. If the technology remains the same it will be left behind by the innovators who develop better technology to catch and then pass the rivals.
Modern day fridge freezers are the same, once upon a time the 3 way ruled the bush, then the 12v compressor fridge, now the 240vac inverter fridge leaves them for dead in efficiency, ability to operate in extreme heat, long life and price. Times change and the manufacturers that attempt to rely on their former glory are left behind in the dust

 I hear what you are saying Terry but I would still look at an engel.

I have a newer model at home as a beer fridge and never had an ounce of trouble with it in 10 years. As you pointed out the compressor is a tad noisy but it's away from the house so that doesn't bother me.

Agree with T1 about the new engel's had the 80/l bought in '06.
Repaired it at 10 mths, broke down 2yrs later, cost $500 then
again 18 mths later thru it in the tip.
Replaced with Techniice 80/l duel zone, 6yrs australia wide part &
labour warranty full stainless and when I bought it was only $1k not $1.9k.
I now never have a cold beer and fridge cycles in 40+C temps doesn't
run 24/7 like the engel did.
Running temps -18 freezer, fridge 1.

 Is that because you can't afford to buy beer now after the $2,000 plus losses from the Engel :lol: Hopefully you mean the beer is always cold and that is the important part, making ice for the honey whiskey is a bonus and if the food can be packed in around the essentials even the boss is happy wink

My 60L Trailblazer was 22 years old when the power unit failed (bought just after the Brisbane Expo in 1988). The new power unit draws a bit more power but still performs well in all external temperatures. At the time Engels were lacking insulation, the eutectric Autofridge was more expensive & the TB was about the best of the "bunch".

So who is using a domestic fridge with inverter technology through their inverter these days ...???

Makes ya wonder,, 5 or 6 hundred bucks compared to 3k for a 12 /240 volt under bench job ...

And bold folk bin there done that , lookin at a Haier 198 ltr at the mo , but read a couple reviews ,not real flash ...???

LG's smallest I can find is a 254 ltr ,gettin a bit big for my LWB Sprinter ...???

 Our 80 litre TrailBlaza  is still in use (as a freezer or fridge)  at home .....bought new in 1988 also. Tough unit.  Great "Backup Service " as well.  KB

I have had both an Engel and Waeco. I got rid of the Waeco as it did not compare to the Engel fridge or freezer settings.

Had the Engel about 15 years now and can't fault, however, if it carked it, I would look at the Brass Monkey. Friends have it and quite good plus it fits under the Wildtrak tray+ battery as well.

 There are quite a few using domestic fridges with an inverter. It's been discussed recently, use a small dedicated inverter just for the fridge for efficiency. If you need a large inverter for cooking then get one for that task.

 Hi Vik, 

Almost 7 years ago I chucked out my 90ltr 3 way and replaced it with a Samsung DI 228ltr domestic fridge.

Fridge cost $290 new, Vicron 350va Inverter new for about $100, 3x100watt solar panel, a Morningstar Solar controller, a 2nd 100ah battery along with meters of 6B&S cable and anderson plugs. I didnt add up the total cost but bit over a grand.

best mod i've done

" use a small dedicated inverter just for the fridge for efficiency "

Now thats an idea...??? I have a 2000 inverter now and will have an induction cook top and 12 /240 volt water heater ... Dont mind turning off the water heater when using the stove or micro, but the fridge must stay on , too easy to forget ya turned it off in my senior years ...

So gundog, is that fridge DI 228 job inverter tec, ? seems a bit old for that ??? So doesnt suck too much juice then it would seem ...

Yep, reckon I will go the domestic way , does the door open when ya drive ...??? not that would be a big deal to cure ...

Yep, reckon I will go the domestic way , does the door open when ya drive ...??? No 2 child proof locks from the big green shed

not that would be a big deal to cure ...

I'm looking to buy a 2 door fridge freezer combo unit..., something around 60 or 70 litres...., something that will handle corrugated back tracks.
Cant seem to decide on one...., YET.

Have an 8 year old 60L Chinese made Waeco clone (6th Gear). $400
Same Chinese made Danfoss compressor, same Chinese made electronics (probably from the same Waeco factory like diesel heaters).
Hasn't missed a beat. Has been in the back of the fourby over every one of the worst roads in Oz.
I've always run it as a freezer in the main compartment at minus 15C and the smaller fridge compartment just gets overflow cold at 4C.
Works a treat.
