No it's not fiberglass, I think aluminum. It was a show special with scratches, but new warranty.

Failing thermistors used to be the Achilles heel of Waeco fridges (and may still be I don't know). Bloody $2 component would fail but couldn't be replaced as it was built into the case so throw away otherwise perfectly good fridge .
For this reason I've never bought a Waeco (but have had 2 Engels for over 10 years with no problems at all).

How would you have felt if the 60L ARB failed 2 weeks after the warranty and you were left holding the bag ? I'd reckon this would be a good reason to question the ARB's longevity and consider an alternative (as you are doing now).

As a technician (retired) I'm pretty conversant with electrical units and their meanings and I can tell you that there is no such unit as A/Hr. This is just meaningless drivel, complete and utter bull **** , though it is regularly used by some 12 volt fridge manufacturers to 'promote' their products. I tend to steer clear of these products as the company either have no idea what they are talking about or are trying to baffle a prospective buyer with seemingly plausible bull ****. Both good reasons to look elsewhere.

Meaningful power usage can be expressed in watts or as an 'average' current draw in Amps.

Why not ? I'm not trying to get into a Waeco/Engel type argument here but Engel make a very good product IMO superior to many of their competitors and have the 'runs on the board' to prove it.

So install another battery . Not an issue whilst traveling as the alternator is doing all the work but can be a problem if immobile for a while. Depends on what sort of traveling you do. On extended trips vacuum sealing may not be an option though there's nothing like pulling up to a campsite when it's stinking hot and removing the 'Glad' iceblock bag from the freezer and 'clinking' a couple of ice blocks into the Chardonay to SWMBO's pleasure and the envy of surrounding campers.

Don't worry about it, leave the 240volt adapter at home (or don't buy it in the first place) and connect a 240volt battery charger to your 'house battery' instead and run the fridge(s) off 12volt all the time. Achieves the same end with the added advantage of having a battery charger if needed.

Ditto re Engel. Our 15 year old Engel in the camper was still within manufacturer's specifications when I had it serviced last year.
We added the Evakool in the Defender because it means we have the choice of two fridges or a fridge and freezer. They run off separate batteries and both can be solar charged. We ran both in summer heat on Straddy at Christmas with no problems.

I recently brought a RF60 as I was chasing the low profile, my Engel is just to high for the new application.....haven't used it a lot but a mate uses his heaps in a boat and cannot fault it.

I too see no reason to run freezer while touring

I find I have had to run it at zero instead of 2 degrees like the engel.

Even though it comes with a 240v adaptor you won't need it....I'm surprised how quickly it pulls down to temp.

Plus I like to support Aussie manufactured. Oh and I brought a seconds, just need to swap the hinges to the other side.

Thank you Deano ..... if I may ...

1 - "How would you have felt if the 60L ARB failed 2 weeks after the warranty and you were left holding the bag ? I'd reckon this would be a good reason to question the ARB's longevity and consider an alternative (as you are doing now). "

My 47L ARB was a version 1 unit. The replacement was a version 2 unit. Version 2 units had replaceable thermistors. ARB replaced many version 1 units outside warranty as it became known as a genuine manufacturing fault/issue and they did the right thing by their customers. I give them brownie points for that. Haven't really heard any bad rap about ARB fridges, a bit about Evakool (customer service/warranty related - not the actual fridges operation) ... and a few family members who have bad runs out of _newer_ Engels ... older Engels appear to be way more reliable (read bullet proof!) ... plenty of evidence to back that up!


2 - "Meaningful power usage can be expressed in watts or as an 'average' current draw in Amps."

Yeah I know. I'm a techie too ... 0.87A/Hr ... meaning the fridge draws an AVERAGE current of 0.87amps per hour every hour per every 24Hr period. Running can be anywhere from 3.5Amps to 5.2Amps whilst running ... but it doesn't run non-stop for 24Hrs, does it ?. I should have qualified my statement by saying "per 24Hrs" ... my bad

I've actually logged my 47L's performance ... Fridge 3/4 full of drinks. Set at 3deg (measured with a separate fridge thermometer) Battery starting voltage of 12.99v. Temperature logged as a min' of 21degC and a max' of 28degC over 5 days test period. Battery capacity of 210A/Hrs. Temperature and voltage checked same time each day. Test ceased at 12.35v (with fridge not run for 2hrs). 12.35v on my battery bank is approx' 65% state of charge. 35% used is approx' 73.5A/Hr. Divided by 5 days = 14.7A/Hrs per day average (that's 0.6125 A/Hr average over 24Hrs without the fridge being opened). When travelling I allow for 1-1.5A/Hr per day (24-36A/Hrs useage per day) and the kamper is not parked under cover, but outside in the sun. 12.2 volts on my setup is 50% state of charge. 5 days parked under cover in a garage. 3 days whilst outdoors for my battery capacity with some breathing space.

3 - "Why not Engel ... ???"

Costs too much! For the price of a 60L Engel I'd buy the 52L National Luna. The ARB lists for $426 less than the Engel, the Evakool would cost me $606 less than the Engel ... 60L Engel fridge opens the wrong way! Weighs too much (7.5kg more than the ARB/11kg more than the Evakool)! Never said there was anything wrong with Engel ... but "not interested" as for my application there's better choices ... hence my question. ... Waeco got off the short list pretty much early in my research. I think the ARB has superior insulation to the Engel though. Just my opinion!

4 - "So install another battery"

Really ? ... 210 in kamper / 135 in D2 ... and can be bridged ... think I have enough, and the extra weight is something I'm trying to avoid! ... and we carry 320w of solar which can be run as 200w on the kamper and 120w on the D2 (or as 320w on the kamper) so, so far power's never been an issue. We're either touring day by day with the odd 2 day stop over OR a week in one spot. The 47L could be run as a freezer if we really needed, but we don't drink Chardonnay Vac' sealing & refrigeration covers us for the longest we've ever been off the grid so far (and taking more than 3 weeks or so off work is almost an impossible task) hence the "don't _need_ a freezer" comment ... but could if we wanted when using 2x fridges. Hence the Evakool question as it can be run as a combi fridge & freezer whilst still leaving the 47L as a fridge.


5 - "... leave the 240volt adapter at home (or don't buy it in the first place) and connect a 240volt battery charger to your 'house battery' instead and run the fridge(s) off 12volt all the time. Achieves the same end with the added advantage of having a battery charger if needed.

ARB gets points for having 240v built-in. No external adapter needed. Kamper already has a battery charger on board. Moot point. Plug in 240v, ARB automatically switches to 240v operation .... gotta plug in 240v at home to look after the batteries anyway. Fridge in the D2 wouldn't be in use when at home so no issue ... Evakool would need to be changed over manually IF wanting to run it on 240v.


Like I said ... done plenty of research. narrowed down my choices, and have good reasons why I've ended up where I have with my short list.


And ... Not having a shot, just addressing the points you raised. LOL!

Have done plenty of research ( as I did when shopping for the 47L which had to fit end on into the back of the D2 ... again, side opening wouldn't work for that application either) and asked about the Evakool as I have nil experience with that brand, and was hoping for some collective wisdom from the forum ... because $180 saved is $180 saved ! ... IF it's a wise saving, NOT just a saving for savings sake.


Thank you for your input ! Appreciate it

Just go the Engle then forget about it,all done.

Mine has done 35yrs,one of my brothers 38,both never missed a beat.

I ran into a Truckie last week that was on his third Waeco in 5 yrs.

Edit,didn't see the above post...LOL

Thanks Weeds !

The ARB 47L temp display _may_ be out by 4degC ... says -1 on display, fridge thermometer sat in middle of cabinet says 3degC. Set displayed temp accordingly. The profile height wasn't too much of an issue (the 47L is higher ... as high as the 78L ARB with the 60L footprint, so it would also fit, but it uses 25% more _average_ power and 78L + 47L might be a bit overkill for 2x people ... smaller fridge kept full is more efficient than a larger fridge partially empty.

How does the RF60 appear to be on battery usage ?? Plenty of good stuff on forums about how well the RF series work ... still unsure about battery usage and after sales ...

Like to support Aussie as well ... when viable ... and the "seconds" version would cost me $80 + freight more than a new one WITH the lid set to hinge at the compressor end and the 240v power supply included ... I'll take a new for less than a second any day!


Thanks !

we have a 60l evacool, just resting in the shed ATM but has run for 7 years continues. It run 5 years while in WA including a couple of years in Broome as a fridge freezer sitting in the back of my d1 or later d2. It did have a dry joint in the first month of owner. tech support was brilliant, while in Perth I thought the power pac had failed and rung tech support (fridge at the time was maybe 6 years old), the problem turned out to be the socket (replaced by me for Anderson plugs), they didn't charge for the service (checking power supply and fridge)
