UPDATE Time - YAY!!!!!! Once back from the big trip, I had a punch list of items to take care of from lessons learned. One of the more frustrating items was my new ARB 63L Fridge/Freezer. The night before the trip, I turned it on to get down to temp - it was at 64F. Note, when I installed it, I used the ARB screw in connector and the ARB wiring harness and I wired it to a 25a toggle switch on my console - this way I wouldn't have to constantly plug it in and unplug (my fear was prematurely wearing out the connector port on the back of the fridge).
//
I flip it on, it powers up - all good. When I get up in the morning and go to load the fridge (11 hours later) I notice it is still sitting at 64F - ******? It's not cooling off. This begins a frantic series of text messages with Will who owns Sierra Expeditions because we are literally leaving in 2 hours for an 11 day trip and my fancy new ARB fridge is not working. Will hooks me up with a direct connection in ARB Tech Support. Give him a call and explain my situation. He tells me to unplug from me vehicle and plug it into the wall. I do and it instantly starts cooling off. He says the issue is the wiring in my truck. I counter with I don't think so because my batteries and alternator are on 00 and 4 and I'm using the ARB 10gauge wiring harness and ask if the issue could be with the 12v side of the fridge board? He replies that it could be and instantly starts trying to find me a replacement fridge in my area. No dice - and I'm literally now 20 mins from having to leave. This is when ARB went way above and beyond. He asked me what our route was going to be and where we were staying when. I gave him our first two nights in UT, but then once in CO we were going to be remote for a week. He hung up and called me back 10 minutes later telling me not to worry - he found a replacement fridge with an outfitter in UT and they are overnighting it to the hotel I would be at the following night. Sure enough, when we got there, the ARB was sitting there waiting for us.
//
Interestingly, during the two days of transit across UT prior to getting to that hotel, the fridge was suddenly working flawlessly - really cold - so I was wondering if perhaps you're supposed to plug into a wall first to activate something in the 12v side. This made me all the more convinced that I was right and ARB tech was wrong because if the wiring in my truck was the issue it wouldn't be working. I was hesitant to swap it, but since they went to all the trouble to get it to me, I swapped it out. I plugged it in in the room first and it started dropping temp pretty fast so all good. In the morning, I swapped the fridges and loaded up the new one and off we went for the rest of UT and then Colorado that night.
//
The fridge performed flawlessly Saturday, Sunday, Monday, Tuesday - but we stayed in a hotel room Tuesday night (long story but the trip through CO got cut short) so we ate breakfast at the hotel before taking off. Then a few hours later, we stopped for fuel and my girlfriend wanted something out of the fridge - so I opened the tailgate and it was at 60F!!! Oh crap. Opened it up and all of our meat was completely thawed out - since I didn't know for how long - I tossed the meat out. It was then sporadic. There is no way that TWO ARB fridges can do this - back to back, it has to be something in my truck.
//
Once we get home, I call ARB back and they walk me through a few things. I'm still scratching my head as it works perfectly plugged into a wall. Then I noticed it works for awhile during my truck running, it shuts off when I turn my truck off, and it turns off after my truck has been running for about 30 mins. So - I rip apart my console and find the issue. When I wired in the toggle switch - I connected the ARB 10gauge wiring to a power/ground block and ran 14gauge wiring to and from a relay to the switch. The relay was shutting down from the amperage overloading the 14gauge wiring. So, I removed the 14gauge and replaced with 10gauge, removed the relay (it has a fuseable link anyway) and wired straight to the switch. Tah - Dah!!! It works perfect now. So - ARB was right - it was the wiring in my truck.
//
But, it is impossible to overstate how awesome ARB was through the whole ordeal and hot swapping a fridge on the fly in the middle of UT was something I won't forget - they won me over as a raving fan.
//
Now, thinking through my little situation, I thought it would be really nice to know whether or not my fridge was working while I was driving, but my fridge is in the rear of my Avalanche and completely out of sight. However, it turns out that ARB makes a remote digital monitoring gauge that wirelessly receives signal transmitted by the fridge and shows you what's displayed on the fridge temperature AND also shows you the voltage the fridge is receiving at any given moment. Said monitor is also blue backlit for easy night viewing. It is a really nice design and it comes on when the fridge powers up. It comes as a 12V cigarette light plug in, but I cut that off and hard wired it. It has a mounting base with adhesive to stick to a surface for mounting. The dimensions are the exact same as those on the front of my never used ash tray - so that's where I put it (I'll decide if I want to mod the ashtray later and flush mount it. In any event, if you have an ARB fridge or are thinking of getting one - get it, but also get the remote monitor.
