[Grench]

I have also considered getting two MT35s with expanders and using one for a fridge the other as a freezer instead of a single MT60.

So... my biggest fears with moving to an Engle system? The unkown. My main yearly trip is kayaking with a big group of drunkards. We camp 4 days & 4 nights. One day is spent golfing 18 holes with sand greens. Two days are spent kayaking. The other day is 1/2 on the front & half on the back of the trip. The end effect is that I pull into camp, park and the next time the engine is started is 3-4 days later. I'm the cook for 16-20 people.

Right now I'm using a 60 and a 120 quart Igloo 5 day coolers and it gives me about the right volume to feed 16 people for 4 days in very high style and room for beer for me and enough ice to hold it all cold for 4 days in 110* heat. At the start of the trip though about 60% of the cooler space is in ice. I consolidate to the 120 quart unit on day 3. Yeah, thats about 100lbs of ice right out of the gate.

I can look at a cooler full of ice, shove my hand to the bottom and get a good idea of how it's holding up. Thats a lot harder to do with a battery.

The coolers sit in the shade under a tree with breezes blowing in off of a river. The Engel(s) would have to sit in a locked and sealed FZJ80 in 110* heat with the inside of the truck approaching 150*.

Running an MT60-combi on a pair of Optima D31A batteries, will I be able to get 4 days of cold without running the truck? In 150* peak ambient conditions (to the fridge).

Are Engle fridges so efficient that they can hold cold on a single battery for 4 days? I.e would I be able to throw it strictly on one of my dual batteries?

My third option is to get a medium sized 3-way RV fridge. Then I would need to build it into the back of my 80 with the combustion vent stack running out the corner vent. And mount a 20lb propane tank, etc...

Or I could keep the ice thing going. Decisions.
